But then again, if he doesn't mind restricting his Krita plugin (we're not 
talking about kdelibs after all) to platforms that aren't seminally retarded, 
then it may be perfectly acceptable to use the extension hash_map class.  I'd 
avoid TR1 because it is, after all, not in popular distribution yet.

And just because many KDE developers avoid STL doesn't mean it's a requirement 
for KDE software.  In fact there's quite a bit of KDE software that includes 
STL in one form or another.
