Hi,
Basically, I want to be able to write in a perl script:
print VALUE, "\n";
and have it print out the value returned by a subroutine. Something like
(which won't compile):
use warnings
use constant VALUE => foo();
print VALUE, "\n"; # print 42
sub foo {return 42}
But all that produces is (as is to be expected):
Undefined subroutine &main::foo called at try.pl line 2.
BEGIN failed--compilation aborted at try.pl line 2.
I could do:
use warnings;
print VALUE(),"\n";
sub VALUE {return 42}
but I want to write it as:
print VALUE, "\n";
not :
print VALUE(), "\n";
That is - all I'm really wanting to do is avoid the brackets ... but I don't
know how to achieve that.
Any help appreciated.
Cheers,
Rob
