prog-mode-p?

prog-mode-p?

[T.V Raman]

At present, one can look up the "parent" of a derived mode  via the
symbol's property list as in:

(get 'emacs-lisp-mode 'derived-mode-parent )
and thus ascend the parent chain -- is there a shortcut to checking if
a mode derives from say 'prog-mode (my current use case)
or in general check if mode x has mode y as a parent in its derivation chain?

IIIUC you can use derived-mode-p.
