about the profiles feature we would really like to have so we can have

`inherit (x) ...` evaluates `x` only once | 9847 | Fixes | horrors |
inherit (x) a b ...
now evaluates the expression x
only once for all inherited attributes rather than once for each inherited attribute.
This does not usually have a measurable impact, but side-effects (such as builtins.trace
) would be duplicated and expensive expressions (such as derivations) could cause a measurable slowdown.
