Does this has any negative effect to which optimizations the compiler makes?

The compiler turns multiple heads in a case statement so I believe that’s what he means by “help” ie do its work for it

I believe you’re talking about the elixir compiler here?
From personal experience then unrolling can sometimes lead to less optimized code, a good example is the in operator in guards vs unrolling them.

Yeah, and I wonder if this is an issue in the Elixir compiler, since a reasonable simple recursive function shouldn’t take this long for the compiler to unroll it self.
@josevalim what is your thoughts on this.
