I'm afraid I don't really understand your first point:
in reply to Re: using features in a Safe compartment
in thread using features in a Safe compartment
"reval" only evaluates the code and then returns the value.
As my example showed, the code is never evaluated because it fails to
compile due to say not being recognized. My attempt at enabling the
feature in the Safe compartment via use feature doesn't
So using the "say" doesn't work because it evaluates to nothing, and returns nothing.
It works in a standard eval:
The code in your update shows the same problem that I'm struggling
with, namely that use feature is not enabling the feature
in the Safe compartment.
$ perl -e 'eval q[use feature qw[ say ]; say "hello"]'
Perhaps I should rephrase the question: how does one get use feature to work in a Safe compartment?
