This is a repost from PR 3775:
Something that I think would be useful for addressing this issue is
a fold or fold_symbols

I see why this is a bad idea - the bound symbols only should be remapped,
not the others or else a cached result for one

You and I are thinking of doing in different ways. I would just start out

I think that perhaps they should compare unequal. Making them equal would
be inconvenient. For example, pretend for a

The hole in your argument is that if Integral(exp(-x**2), (x, -oo, oo)) !=
Integral(exp(-y**2), (y, -oo, oo)), you can

The question about ordering of limits in multiple integrals is in the same

My view is that dummy symbols shouldn't make a difference when comparing
objects. In Integral you don't change all
