New features in bleadperl
I added two features in bleadperl recently:
# new prototype character !
# _ is just like $, except that it defaults to $_:
sub foo (_) {
print "<@_>\n";
}
foo(42); # prints <42>
foo(); # equivalent to foo($_)
And another one, you can now override readpipe()
BEGIN{
*CORE::GLOBAL::readpipe = sub($){... }
}
qx/foo/; # calls the function with "foo" as argument
`foo`; # same thing
help them think they understand.
