Are you talking about just the code introduced in commit
2014-04-03T00:18:08Z!dancol@dancol.org
(01ae0fbf30b74e2490144fceabbf5bc5d96f1ba7), or is some other code involved? I'll
CC this to dancol to see if he has thoughts.

I installed a patch to master just now to do that.

Can you give an example of that problem?

Do you mean evaluated as in macro expansion, or evaluated as in execution at
runtime? If the latter, I don't get the problem there. Many other macros assume
that arguments are side effect free, and some of these cannot be turned into
inline functions easily.

Sorry, what's the Fclrhash bug?
