I see. I thought it was parsed inside the function, but if it's parsed
before then quoting is the only option.
To Keith: no, I mean it like this "A + B => C" which is translated as:
"the union of A and B is sufficient for C" in set theoretic language.
The "=>" operator means sufficiency, while "<=" means necessity. Quoting
the expression is good enough, I was just curious if the quotes could be
made redundant, somehow.
Thank you both,
Adrian
