Hello Map-Happy Monks,

I thought I could extract a subset fom a list by doing this:

my @allFruit = qw/apple apricot banana coconut/;
my @someFruit = map { if ($_ =~ m/^[ap]/) { $_;} } @allFruit;
print "no. of some fruit: " . scalar(@someFruit) . "\n";
print "some fruit: " . join('*',@someFruit) . "\n";

This however produces this output:

no. of some fruit: 4
some fruit: apple*apricot**

[download]

rather than

no. of some fruit: 2
some fruit: apple*apricot

[download]

which was what I wanted.

What would be the best way of doing such extraction?
