no implicit;
(Or 'no implicit print;' after rev 2 comes out. ;-)
If you really only wanted to turn it off for one line, you could assign
the result to undef.
undef = open(Foo, "Bar");
undef = $x++;
I tend to use this in a variety of places, but not for a big block of
code. (Mostly because I don't have the scoping issue fixed, so I get
all the spurious dumps from calls I make as well. I'll have an RFC for
that, too, which will hopefully allow me to impliment this as a module
vice a pragma; I've another RFC coming with a similar, (but more
valid, you'll be glad to know) issue); mumkin tomorrow.)
