My point was actually not to have atoms as strings (and prolog filenames).
If I'm reading the EEP correctly: a local atom would actually require a
larger heap space than an equivalent heap binary .. which is a feat all by
I gather that could be remedied though. Haven't looked at the code.
I agree that atom gc is needed but it shouldn't be an excuse for using
dynamic atoms instead of binaries. Besides, if locals atoms are larger than
binaries why would you use atoms. (I might be wrong about the size though
.. didn't look that hard).
