I upvoted your post above, but still your regex m/(\b(?:[A-Z]+(?:\s+[A-Z]+)*)+\b)/g made me squirm. Whenever I see sequences of nested quantifiers like that:+)*)+ I get uncomfortable, remembering various pathelogical cases I've constructed in the past.

To that end, I thunk again, and came up with this which I believe meets the 'spec', whilst avoiding the nested quantifiers;

m[ ( \b [A-Z] (?: [A-Z\s]* [A-Z] )? \b ) ]gx

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
