How exactly is this a big problem? Is the parser always working from left to right and assigning a token on current context or is it looking at the whole line? Is it impossible to give the ternary operator a higher priority than the namespace operator? Then the implementation could always treat foo:bar as being two constants in the ternary. This way only new code not using whitespace would throw parsing errors which actually means that NO existing code breaks. OLLi
