Heh, then don't put large strings. We all know that such code stinks :)

Huh? What does MC for?
I could complain about keeping one plugin code divided by two
different source control systems. It seems very impractical.

Yeah, and i'm the one of them. ;) I wrote a small plugin which
requires a platform dependent code.. To my experience its much easier
to code it in external editor and at some point, after debugging, put
it in some method as string and forget about it.
Then it can be shipped with plugin code rather than shipped in two
different parts with tons of instructions how and where to unpack
sources, what modify in makefiles e.t.c e.t.c..

Ohh, i really don't know.. Maybe we should step aside and use idst for
building new VM?
Ian mentioned previously that he will welcome an efforts in this way.
But this means refactoring all VM code from scratch..

I'm just asking myself, when we could finally get rid of burden of C?
