Description Aurelien Fredouelle 2019-05-11 08:51:53 UTC 
Other common implementations of memoize usually allow to reset the cache. For example, this is quite common in python:

@memoize
def square (x):
  return x*x

square(2)
square(3)

square.cache.clear()

It would be helpful if we could accomplish the same with std.functional.memoize.
Comment 1 Aurelien Fredouelle 2019-05-12 12:01:54 UTC 
Just tried implementing this by making memoize a struct with a static opCall: https://github.com/dlang/phobos/compare/master...AurelC2G:19859-memoize-cache-clear

However I ran into bug #18289, so this doesn't work as-is.

Any suggestions?
