Re: My function needs to be sourced twice. Why?

Yes,

I'm answering my own mail : the function was already defined elsewhere (I had written a file in .vim/plugin/ where I wanted to define this function, and I had forgotten to remove it. I just lost 2 hours :$

Hmm -- it seemed to work fine for me with but a single sourcing.
However, the results I got were

g:foo                 #1
g:foo                 #0
g:foo                 #1

which seems correct to me (a quiet initialize g:foo to zero, toggle to
1, toggle to 0, toggle to 1).
