Paul-C-Anagnostopoulos requested review of this revision.

I added the !filter bang operator to simplify various !foldl expressions and to improve efficiency. It eliminates all the intermediate list concatenations required when using !foldl.

I updated the Programmer's Reference and wrote a test.

I used the new operator in various .td files.
