I think the problem is that f() is returning 2 values, but you alredy have 
a first value on the right ('_'), so 99 is the 3rd.. like this:

_,x = _,1,99

(I just replaced with the result of 'nil or f()'). The list on the right 
gets adjusted, and the 99 is thrown away.

good luck with the regexp :)
