First you agree with me and then you provide in essence the same examples
as Ryan? So what is it now?

Anyway as I wrote to Ryan: the for-in loop is defined as "for VAR in EXPR
do", not "for EXPR1 in EXPR2 do". And even if we would limit it to
typecasts then the next one would come and ask for this or that to be
allowed as well.

No. Nothing of that. There is a variable in the for-in-loop and nothing
more. Anything else currently is a bug and *will* break.

Sven
