Vexing regex question--storing multiple hits for later use

Greetings.

I'm matching a pattern against a long string, and I want to examine each
occurrence of the match.  I know that $& stores the match, but is there
a way to store EVERY match in the string, and then look at them?

Example:

$str = "This is a very long string, isn't it?"

If I want to match against something like /i[st]/ to pick up all the
'is' and 'it' strings, then see what I've got (i.e. each instance), can
I do it?

I've tried to wade through the whole \G /g etc. world, but it doesn't
seem to work for me.

Thanks!
