evil-paredit-mode.el mode map blues

[Óscar Fuentes]

Hello.

I'm trying Evil since a few days ago (looks great so far) and, as a
heavy user of paredit.el, I'll like to avoid the possibility of damaging
the structure of my Lisp code with Evil commands. A quick search reveals
the existence of a small hack named evil-paredit-mode:

https://github.com/roman/evil-paredit/blob/master/evil-paredit.el

but, after visiting a Lisp file and executing M-x evil-paredit-mode, at
first it seems that it has no effect and M-x x shows that the key is
still bound to evil-delete-char. But after some random edit operations,
the key becomes bound to paredit-forward-delete, as it should since the
activation of evil-paredit-mode.

Why could this happen?

I'm using Emacs compiled from trunk 5 days ago, Evil from latest git
sources and paredit-beta.
