If a GUI button simply executes a function. Tooltip for it could 
be generated from the function documentation.

About being able to use the documentation comment in mixins, of 
course it would be an ill recommended thing to do. But I don't 
think it would become much of an issue since you can hardly do 
that accidently.

IMO, D can already be used more dangerously than even C++ if you 
want to: binary imports, string mixins and static ifs can be used 
for far more sophiscated hacks than the C preprocessor. But it 
does not matter since they do not encourage or trick anybody to 
do the said hacks.
