So what do we do in the case of:
print f();
wantarray() should clearly by true, but there are no variables that we
can alias.
This could be worked around by creating an alias to a transient
anonymous variable, which is then passed to print upon completion.
However I'm not sure if we can do that without losing performance.
Cheerio,
