: This one. I see a filehandle in *boolean* context meaning "read to $_",
: just like the current "while (<FOO>)" magic we all know and occasionally
: love. I'd expect $FOO.readln (or something less Pascalish) to do an
: explicit readline to a variable other than $_
It would be $FOO.next, but yes, that's the basic idea. It's possible
that iterator variables should be more syntactically distinquished than
that. One could, I suppose, make up something about $<FOO or $<FOO>
meaning the same thing thing as $FOO.next, for people who are homesick
for the angles, but I haven't thought that out, and don't even dare to
mention it here for fear someone will take it as a promise. Er, oops...
