Re: PARI 2.6 syntax 2: [f(x)|x<-a,b(x)]

A naive question. What about [ 1, 2;
3,4] if it is sensible to space ?
Every such situation should be taken in account.
Why not quotes for reserved words as "in" ?

I care about backwards compatibility ... if not, many exercises
that are using Pari in WIMS would be potentially broken !

This might be a good occasion to declare spaces as significant in the
lexical analysis step...

If at all possible, let's *please* do this.

It would break backwards compatibility, but are
there really people who write

b   =
1 2
when they mean

Possibly a subset of the folks that hammer nails
into their knees in their spare time.
