I think so, because there’s ‘objcode-meta’, used by ‘program-meta’,
which returns a thunk that itself returns procedure meta-data:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (use-modules (system vm program))
scheme@(guile-user)> ((program-meta 1+))
$3 = (() () ((3 7 1 0 #f)) (name . 1+))
--8<---------------cut here---------------end--------------->8---

Thanks,
Ludo’.
