load(true) currently loads
.../share/maxima/5.19.2/share/contrib/gentran/test/T.mac .
Two problems here. First of all, it is using the internal print form of
true (T) rather than the Maxima print form.
Bigger problem: load(true) is almost certainly a user error, where the user
should have been quoting the argument. For example, load(simp) will load
T.mac above.
I would recommend that
1) we rename the file T.mac to something else
2) we give an error for a boolean or numeric argument to load
3) that load use the Maxima print form of its argument, not the Lisp
print form (not sure if there are any other cases that matter here)
More radically, I'd like to recommend that load only accept a string
argument, but that would probably break too much code and too many
habits....
