Inconsistent array casting

[Announcement]

Short arrays aren't enough to loop

[to 10] does what expected and so does [.. for [0 to 10]]

But in contrast...

[.. for [to 10]] throws

Parse error on line 1: Unexpected 'FROM'

Just FYI: [.. for to 10] now works thanks to #859

[.. for to 10] works, but [.. for [to 10]] still doesn't; shouldn't this remain open?

Lexer black magic rewrite is to blame. Specifically, lexer.ls:868 skipped a square bracket (oops!) before any "official" rewrite takes place (oops again!).

IMHO this kind of thing belong to the parser. However a refactor would be non-trivial and requires attention from @vendethiel .

I also agree that this should remain open as it is certainly a bug.

I am going to patch this temporarily with a grammar fix.
