Thank you. The useful note about CORE, in particular, is new to me.

Hello Shawn, thank you for answering.
I'm sorry, I was a bit sloppy with my example and so maybe unclear about my
question ...
It's not about the precise syntax of getting a reference to a subroutine, but
rather a subroutine in a module.
For example, this pgm is clear:
#!/usr/bin/env perl
sub
Hi,
I'm experimenting with Math::Trig and would like to be able to pass the
function in as a parameter:
$f = $opts{f} || &sin;
...
&$f($w);
Undefined subroutine &main::sin called at (eval
9)[/usr/lib/perl5/5.14.2/perl5db.pl:640] line 2.
I have also tried:
$f = &Math::Trig::sin;
I'm trying to install UR-v0.12 - and encountered a great wizard. But I don't
have root access on my machine. I get
You are not allowed to write to the directory '/usr/lib/perl5/site_perl/5.8.8'
even though I'd entered
Your choice: [] PREFIX=~/lib/perl
Can somebody please explain to me
