Function template make_expression_function



// In header: <boost/yap/algorithm.hpp>

template<typename Expr> auto make_expression_function(Expr && expr);


Returns a callable object that expr has been forwarded into. This is useful for using expressions as function objects.

Lvalue expressions are stored in the result by reference; rvalue expressions are moved into the result.

[Note] Note

make_expression_function() is only valid if Expr is an expression.
