You can't. Use SFINAE instead, it's basically the same thing. -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated. First time posters: Do this! ]

As Mathias says, "enable_if" is just a consistent way to use SFINAE. The code has no real boost dependencies and you could copy or write it yourself easily. On the other hand, it isn't all that useful without some type traits libraries which you don't want to write yourself. If you are able to use TR1 (for example, with Visual Studio 2008 SP1), then you can get the standard type traits without any external library dependencies. Worst case, you could also copy/paste any type traits code you need as it is mostly self-contained (though often compiler dependent). -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
