No, this is different.  Think of eval([        1 + 1]).

This is dead broken, extremely bad, puke!  Never ever put features for
novices which can make it harder for real hard core programmers.  M4
programmers are aware of the rules, and having an exception is a means
to have unwanted phenomenons remain hidden.

I really don't want soft corners.  But that's my HO.

Nope :(

I thought it did via IS_SPACE, but I didn't look at its meaning since I
was to remove it.
