Let us just be clear. You mean the request to allow the first inlet to be a
float or symbol variable (such as $f1 or $s1) rather than a signal ($v1 for
expr~ and $x1 for fexpr~) - right?
I think this means it would be a bit confusing not to use the first inlet

Hmm, I see that now! Unlike secondary inlets, which would not allow a
signal connection, the left/main inlet would still allow it. So this is a
good reasoning... in fact it'd be better if it would not allow a signal
inlet, and that would require too much surgery.
Anyway, I only brought it up cause it said so in the source code this could
be considered in the future. So yeah, just leave it as it is and remove
that remark from the source code.

It's coz it doesn't have CLASS_MAINSIGNALIN in the setup method. But expr~
has it, so it converts floats to signals.
So I just added CLASS_MAINSIGNALIN(fexpr_tilde_class, t_expr, exp_f) to
fexpr~'s setup and it worked fine.
Though now I think the class_addmethod(fexpr_tilde_class, nullfn, gensym("
signal"), 0) is unnecessary, as well as it is not necessary for expr~.
Well, you and Miller should know better, I must be the most ignorant object
developer for Pd :)
