<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">What is the difference between _() and i18n()? The example shows one to be ordinary text and the other having a placeholder, but they should be synonyms.
Since _() is native Gettext convention, other synonyms in the same vein would be p_() for i18nc(), n_() for i18np(), and pn_() for i18ncp().
(Just to be sure, are translations fetched later really through KDE i18n calls? Only then should calls have i18n*() names.)

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Well, there is no i18n() function in the template system. The _() syntax is not really a function call, but just a syntactic marker indicating that the string should be extracted and run through the translation system. The _() syntax can also not take any arguments, so it is always ordinary text and can't handle placeholders. This is similar in semantics to how the django template system works.
{{ _("translatable string") }}
is a shortcut for the 'template tag'
{% i18n "translatable string" %}
Not the use of {{ }} in one case and {% %} in the other. These are the two types of parsable tokens in the syntax. {{ }} is simple value substitution and {% %} can be anything, like value substitution in the i18n case, or more complexity in the case of the 'if' tag:
{% if something %}It's true{% else %}It's false{% endif %}
Arguments to tags are separated by whitespace, so as you noticed we can have
{% i18n "The time is %1" the_time %}
But we can't do the same with _().
Because _() is not a function call that can have arguments, the additional syntaxes you proposed (which require arguments) don't really belong.
The translations are fetched later through the use of KLocalizedString such as approximately:
QString translateString(const QString &input, const QDateTime &arg)
{
KLocalizedString ls = ki18n(input.toLatin1());
ls.subs(arg);
return ls.toString(d->usedLocale);
}
And that is called with approximately:
QDateTime now = getNow();
QString result = translateString("The time is %1", now);
I'm simplifying this of course for this example because I don't fully understand the nature of your question. I'm not certain how this affects your comment about whether the tag should be called i18n or not.
I generated documentation for the development version and put it online. It may clarify this stuff further:

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Your explanation answers my question perfectly. The distinction between {{ }} and {% %} slipped my mind; and _() and i18n are indeed synonyms under the hood (both using KLocalizedString, with proper parameter substitution as required). Ignore my mention of p_, n_, np_.
(A detail off topic: it should always be ki18n(someqstring.toUtf8()), in order not to needlesly constrain the original text.)</pre>

So is that a ship it from you?</pre>
