Since BB is not using Coco, I cannot imagine
how to get Coco involved here.
I think it is a hand-coded transformation of the abstract syntax tree
that the BB compiler is building during parsing.

Can such a transformation be done using Coco, as suggested by Aubrey McIntosh?

yes!

Usually operator overloading would transform the expression like
z:=a+b*c;
in something like
z:=a.Add(b.Multiply(c));
If math operations are overloaded like
PROCEDURE "+" (IN x, y: COMPLEX; OUT z: COMPLEX);
z can be expressed as a sequence of two statements
"*"(b,c,tmp);
"+"(a,tmp,z);
And the compiler should be able to transform one statement like z:=a+b*c; in two statements as above internally. Is this what are you saying, Josef?
