Comment(by schilly):
Ah ok, lol. I've also complete a ptestlong and it's just this f(x) is or
== f thing. I also think that this depends on what f is. if f is already
an "f(x)" then f(x) should be the same as f, otherwise not. Behind the
scene it is symbolic_expression(f).function(x) and I can only speculate
that it makes sense to make this function behave idempotent, but only in
special cases. Sorry that I don't know more about this and I also cannot
comment on the code itself, apart from that it is apparently working for
me ;)
