" TODO lots more keywords
" global, self, etc. are special *objects*, not functions. They should
" probably be a different color than the special functions
" Actually, should cvtstr etc. be functions?! (change tadsFunction)
" Make global etc. into Identifiers, since we don't have regular variables?

" Remove any old syntax stuff hanging around
syn clear
