1. why perl doesn't have a built-in strip() function?
each time I need to say $var =~ s/^\s+|\s+//g to strip
Good question. Perl 6 is fixing this by adding a 'trim' operator.
The code I use is
for ($var) { s/\A\s+//; s/\s+\z/ }

You have a missing delimiter there.
2. what's the standard module or method to generate a random string, for example
the string will be used as part of url.
If you want to use the string in a URL then it cannot be truly random, because
not every character can appear in a URL.
That does not make sense.
Why not just generate a random number and use that as the string?
How is that different?
