Re^2: syntax for calling a function

[alexm]

&foo;
sub foo { print "Hello\n" }

Don't forget that the following calls are identical:

&foo;
&foo(@_);
foo(@_);

Therefore, &foo; should be used with care (passing @_ explicitly is much more friendly, IMHO).

Update: chromatic is right, I should've checked perlsub before posting.

Don't forget that the following calls are identical:

They aren't, though. The leading & explicitly bypasses any prototype checking. &foo(@_) may be very different from foo(@_).
