If I'm not mistaken, [inlet] and [inlet~] are members of the same
class "vinlet," which has the two constructors vinlet_new and
vinlet_newsig. Similarly but somewhat differently, all the
expr/expr~/fexpr~ stuff is collected into a single set of vexp*.c
files. I didn't mean to say "vexpr", and I guess expr has different
classes underneath so it's not fair to say it's one object class --
but in both of them there's a "several objects collected here" kind of
feel which made me wonder. Maybe this is all just a coincidence. I
could see the "v" in "vinlet" standing for "visual" to distinguish it
from the more generic "inlet" class.

Thanks, this explanation makes a lot of sense -- I knew what they did,
but not why they were called v____.
