How to test whether something is a valid identifier in Python3? I
don't know.
And what shall we do with reserved keywords like "def"? Should
var("def") always result in an error (probably not), or should it just
not be injected into the global name space? Hence, a warning is
printed unless it is var('def',inject=False)?
Cheers,
Simon
