#Environment
    http://gcc.godbolt.org/ with x86 gcc 5.1.0

    #Result of gcc -v 
        gcc version 5.1.0 (GCC-Explorer)
        Target: x86_64-linux-gnu
        GNU C++14 (GCC-Explorer) version 5.1.0 (x86_64-linux-gnu)

        compiled by GNU C version 5.1.0, 
        GMP version 4.3.2, 
        MPFR version 2.4.2, MPC version 0.8.1

#Compiled with option 
    -std=c++14

#The output :
    error: unable to deduce 'std::initializer_list<auto>' 
           from '<brace-enclosed initializer list>()'

    at line : 
           auto list = {args...};

    error: unable to deduce 'auto&&' from 'list'
           for(auto &&a : list)

The code compiled fine with clang 3.7.
The aim of the code is to provide a way to overload lambda.
