How about:
--8<---------------cut here---------------start------------->8---
#!/bin/sh
 guix time-machine -C channels.scm    \
     -- shell --pure                  \
     --development $(basename $(pwd)) \
      -- $@
--8<---------------cut here---------------end--------------->8---

Of course you need to A) have a channels.scm in your project and B) have
your project directory named after the package's name in your channel.

I was using channel too before!  It felt good to pin dependencies to a
version so it does not break while you're developing.  Howeverff, I felt
that the time-machine was taking enormous time everytime a push was made
to a channel.

My biggest usage of the channel was to have the definition of my package
before it was merged into Guix channel.  But this could also be used for
a development version that differs.
