regex - How do I find all tokens in a string that matches regexp in perl?

Question

I'm wondering how I can extract all tokens matching a regular expression in perl and put them in a list? I saw a nifty example on stackoverflow, but I can't find it again (argh!!)

So, suppose:

my $cppString = "  boost::fancyFunc( widget->dooHicky());"

I'd like to be able to extract all \w+ tokens from string. But, maybe later I might want to just extract all tokens that look like "\w+::\w+", or "\w+->\w".

Anyways, what is the readable compact way of doing this given a regexp?

The example (which I can't find) looked something like this:

my @cppTokens = ($cppString =~ m/(regexp)/g);

Anyways, the above example is not exactly right.

thanks.
