Comment (by mmezzarobba):
Actually, I'm wondering if ''all'' symbolic constants shouldn't be part of
a special parent, say the “set of symbolic constants”, with no operations
at all defined on it (so that they can be used only after being coerced to
something else). That would make it easy to support operations like `pi +
1.0`, `exp(infinity)`... with no artificial coercions from `SR`.
