These will keep me busy, it seems you found quite a bit of special cases the compiler isn't handling well, I'll go one by one and clean everything up.

I hope you don't mind if I report a last one... A solitary dot is accepted by the parser, allowing construction of expressions such as 'SIN(.)' or '√.'

I don't mind at all... that doesn't look good.

However, the dot is a valid character in a variable name (like many other symbols), therefore '.' is a valid variable name, though a bit unsightly. The only problem is, if I add the requirement of at least one letter in the name of the variable, it would rule out variables that are greek letters for example (since greek letters are just weird Unicode symbols after all, not too different from the dot). Even banning the dot you could always find some strange unicode symbol that's not forbidden and create a strange variable name like that. I don't know what's the proper solution in this case.
