Re: [boost] BOOST_LOCAL_FUNCTION

What's the advantage to using int BOOST_LOCAL_FUNCTION(char c) { std::cout << c << '\n'; return 1; } BOOST_LOCAL_FUNCTION_DECL(a)

over:

struct { int operator()(char c)const { std::cout << c << '\n'; return 1; } } a;

Local struct can't be passed to templates: boost::function<int(char)> f = a; error: conversion from `main()::<anonymous struct>' to non-scalar type `boost::function<int ()(char), std::allocator<void> >' requested -- Alexander
