FYI, the 2.4 error was
Syntax error - expected to see possibly '=', not a variable

Of course all the code involved here is now public domain (eu.ex
and/or parser.e and/or and emit.e), albeit packaged specially.

An interesting thing to attempt would be to backtrack at the error
point (add zero overhead in the non-error case, please), possibly
looking through the most recently added var names for something rather
suspicious (probably including user-defined types). I'm sure Rob would
thank you if you came up with something clever in that area.

You might even get close to perfection here: point at the comma and
say "that comma should probably not be there"? (But I doubt it
