I read the man page and indeed this is not what -e means!

It turns out I was trying to escape the $(P) and $$(P) did not expend to
anything (but \$(P) did!). After a few attempt, it turns out that the
foreach is executed before the call to eval and therefore $(P) doesn't need
to be escaped!

Neat trick! I was using ';' as a separator and that lead to symptoms I
described. Now it works as expected!
