Right!  If it's important to you to catch syntax errors in
the string separately from those its _execution_ itself may
raise, you can also use built-in function compile first (it
compiles the string into a code-object, raising syntax errors
if need be), then use the code-object as exec's argument.

If

Right again!  If nothing else, because exec is RARELY the right
solution -- it's more of a "quick-fix that I will refactor soon"
kind of thing (most of the time:-)...
