Yes, mutable variables can be easily introduced by some AST translation, but
big problems come from mutable structures. It is much more harder implement
this by erlang and I think things comes much more simple if there will not
be mutable variables nor mutable structures. Mutable variables without
mutable structures will be messy in mine opinion. Mutable variables without
aliasing will be as much confusing as immutable functional world for Reia's
target developers. IMHO learn immutable concept is easier than understand
why something can be mutable and something not. Without mutable structures
solution Reia looks for me not well designed from start idea.
