I'm interested that some 4GLs mix up the scanning and parsing stages.
What 4GLs do you consider to be most deficient in this way? And what
do you consider the most pathological languages? I'm not trying to
start a religious war here, I'm interested in language design - good and
bad!

[It's not inherently evil to mix scanning and parsing, but when you do
so it's awfully easy to come up with a language with a syntax so messy
that it can't be described other than "it's what the parser parses."
