---------------------------------------------------------------------- 
The code is currently written exactly as a regular assignment is in AEL,
which is to wrap it as an express (i.e., the observed $[] behavior).

The idea was to let expressions with math, etc., function directly in the
return line.  But that obviously has other problems I hadn't thought of.

Perhaps the right thing to do here is to NOT wrap it as an expression, but
document that you can't use expressions directly.  You'll have to assign
the expression's result to a variable and then return the variable.

So, assuming you wanted to perform math, this wouldn't work:
return 8-2;  <--- return value would be the literal string, not 6

But this would:
MATHRESULT=8-2;
return ${MATHRESULT};

The other option, though I haven't evaluated how difficult it would be to
code, is to make AEL support a return value in quotes as a string literal.
