I actually get a different error [1], namely that the call line can't be
parsed because we're using a regex to grab call lines and regular
expressions can't count parens.

Exporting a slightly changed file (attached [2]) works for me w/o error.
I'm using the following Emacs version [3].  I may have to wait until the
cause of this error hits the Emacs in the Arch Linux package system to
debug further.

Cheers,

I should be able to put the output inline using call_test('foo).
