Detailed Description

template<typename Rewriter>
struct Fortran::evaluate::rewrite::Mutator< Rewriter >

Bottom-up Expr<T> rewriter.

The Mutator traverses and reconstructs given Expr<T>. Going bottom-up, whenever the traversal visits a sub-node of type Expr (for some U), it will invoke the user-provided rewriter via the () operator.

If x is of type Expr, it will call (in pseudo-code): rewriter_(x, active_member_of(x.u)) The second parameter is there to make it easier to overload the () operator for specific operations in Expr<...>.

The user rewriter is only invoked for Expr, not for Operation, nor any other subobject.
