I'm not yet sure if this change introduces any bugs, and the way I avoided calling
clone
onoriginal
is a bit of a hack and so maybe should just be replaced with doing the obvious thing (i.e., cloningoriginal
). That said, this change allows us to insert nodes into the E-graph duringmake
, which I find useful for a dependent type-checker I am writing, which attempts to do type inference inN::make
.
