This is already common.

IMHO everything below 4 makes the structure of a function unclear :-)

Is a must. In particular because kwrite's default tab width is
incompatible with _all_ other Unix editors.

Is the convention used by Qt and kdelibs and therefore the obvious one.

    "Encoding the type of a function into the name (so-called Hungarian
     notation) is brain damaged - the compiler knows the types anyway and
     can check those, and it only confuses the programmer.  No wonder 
     MicroSoft makes buggy programs."
