Comment:
It'll take me a while to understand the patch, but combined with #12801
and the use of `function('f')(x)` this looks like it will save me a lot of
trouble:
{{{
sage: f = function('f')
sage: f(x).diff(x)(x=1).substitute_function(f, sin)
cos(1)
}}}
I have a ''lot'' of code I can test it against.
