This is related to a subtle, undocumented difference between these two
definitions of a symbolic expression:
var('v')
r(v)=v
print r
///
v |-- v
r=v
print r
///
v
so both are printed different, but they return the same value when
called with a question mark:
r?

These are not both symbolic expressions per se - one is callable, the
other one isn't. These used to be called
