Subject: [Boost-users] [Proto] Functions returning an expression
From: Joel Falcou (joel.falcou_at_[hidden])

I have a DSL defined in proto.
What's the best wayt o build functions that returns an expression made
of this DSl elements.
Like let's say the vec_expr class support+-*/ operators

I want to write

??? f( vec_expr<W> const& a, vec_expr<Y> const& b)
  return (a+b)/(a-b);

How can I easily (aka no nested make_expr call) build the return type ?
