Hi All,

First attempt kind of failed due to alignment:( So this is another one)

So I wrote a library eswitch which provides enhanced functionality for C++ switch. Please take a look and leave your comments.

Motivation: To overcome native switch limitations: 1) one parameter per switch 2) the parameter restricted to only integral types( int, char, enum ... )

Whereas "eswitch" supports any number of parameters and almost without restriction on their type, as long as the type is comparable( i.e. has operator== ).

Why it is important? Because people want to overcome current switch limitation either by implementing their own solution, non-standard extension or even trying to standardize it. Making proposed eswitch functionality part of the Boost-Library will provide millions of developers useful, universal and agile functionality in order to finally fulfill their needs.

Full proposal here: https://github.com/rabdumalikov/proposals/blob/master/eswitch_boost_proposal...

Repository: https://github.com/rabdumalikov/eswitch_v4

I have not looked at your docs or code but I think the idea of a multi-parameter, multi-type switch construct would be useful to many programmers.
