// Templates for deducing, wether a lambda_functor throws inevitably of not -
// This mechanism is needed to make the compiler happy about
// return types of try and catch parts. 

// a lambda_functor throws for sure if:
//  - it is a throw expression
//  - it is a comma expression, and one of its arguments throws for sure
//  - it is an if_then_else expression and either the if statement or both 
//  the then and  else throw.
// (there are other cases as well, but we do not cover them)
// e.g. _1 + (rethrow(), 3) does throw for sure but this is not checked
// This implies, that in such a case, the return types of try and catch parts 
// must match if the try part returns other than void.
// (Such checks could be done though)
