All the energy found in this thread and on this topic should really be spend 
to fix the broken way of storing the algorithm description.

In an ideal world all the code would be stored in a data model which resembles 
pretty much what this is all about, basically the AST. How the storing is 
really done and what language and format is used internally could be just a 
matter of the storage engine and optimised for it.

Then locally anybody would use an editor which is also capable of 
understanding the semantics of the data (and not just a linebased text editor 
with some addons). The editor one could be configed to use any textual syntax 
for the display of the algorithms/AST. Like C++ syntax, specialised with e.g. 
personal spacings and linebreaks rules. Some might even go with graphical 
</ideal world>

But this seems to be still stuck in academics and brains, has not made it into 
the real world of the year 2008, at least in my personal parallel universe. 
Because, fully-automation-based self-hosting code development and storing 
only has been around for some, wait, 40 years or that? Oh, inertia...

(And then there is this ugly linebased preprocessor thing with C/C++, still 
might be solvable with a two-stage approach.)


PS: My wishes for real life: no tabs, per file consistency, self-documenting 
variable/structures/method names, compilable with standard compilers. Thanks.
