Hmm, it's a bit of a strange way to check this, but it's valid code.
So, when comparing functions, we need to ignore any arguments or bound
dictionary that a partial adds.
It's not really nice that two partials for the same function but with
different arguments are considered equal. But it's unavoidable if
comparing the plain function with the partial returns true.
I guess we can compare the string values.
