Great if it helps you. Just beware that this simplified version is not 
exactly equivalent to your initial perl snippet:

Generally, findall will find ALL occurrences of pattern, not just 
adjacent ones.

Since your perl example would never terminate if something non-matching 
is interleaved with pattern matches I figured you never expect that case.
