passing the reference of hash values array

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am not sure if this is possible but I have the code:

my @temparr = values %arr;
my $mean_of_arr = &average(\@temparr);
[download]

I would like to be able to not create the @temparr, if its possible and just do something like:

my $mean_of_arr = &average(\@{values %arr});
[download]

but obviously that doesn't work.

I think you want: `my $mean_of_arr = &average( [ values %arr ] );` `[LIST]` creates an anonymous array ref. but why do you use this old function &call syntax? Cheers Rolf	[reply] [d/l] [select]

yep the brackets worked. thanks : ) Is it better to just use 'average(...)"? I just use the & since it gets highlighted/colorcoded for syntax whereas without the & its just plain black text.	[reply]

yes, IIRC it bypasses some mechanisms like prototype checking ... which editor do you use? Cheers Rolf	[reply]
