Exp10 needs to be refactored

[rtoal]

Currently the following is syntactically legal

7 . 2

It shouldn't be.

What I was discussing with Iko was that is it necessary for it to be a syntax error. As I had it in my mind, this is valid syntax, so it would pass the parser, but it would be in the analyzer where it is determined to be incorrect.

Is this thinking incorrect, should it really be in the grammar that 7 . 2 should not be allowed?

You can do it either way.

But for things that can be restricted in the syntax, why not?

The syntax can certainly prohibit literals before dots, just as it can certainly ensure that the only thing coming after a dot is an id.

It's good practice to tighten things up in the syntax.
