Specify argument names with fun hooks? #163

Open robinp opened 8 years ago

robinp commented 8 years ago

Hello. Is it possible to tell the fun hook what name to use on the various generated arguments? Instead of just a1, a2 etc. Thanks!

Not that I'm aware of, no. Is there a particular reason why you'd need the arguments to have certain names? On Apr 18, 2016 2:12 PM, "Robin Palotai" notifications@github.com wrote:

It would be nicer to read - for example, if there are three Bool arguments, would be nice to give descriptive names to them. Though I found you can put docstrings on the types, which alleviates the problem slightly.

One could argue that the wrapped functions are low-level and probably need a higher level wrapper with proper names - but still feel it would be useful to have descriptive names at the low level too.
