main.d:3 foo=3, bar=4 (or whatever formatting is applied given supplied stringiified arguments, that's irrelevant as it can be customized inside user code) > If that's the case then this seems like yet another hack because we don't > have AST macros. I predicted you'd mention AST macros. While I agree AST macros would solve this and other problems, the likelihood of them appearing in D in the near future is slim. My proposal is pragmatic and can be implemented with a short PR in the near future, if people agree on this change. If/when AST macros come to D, we'd still be able to use them for that purpose. Currently there is *zero* good workaround: * either calling code is ugly (https://github.com/dlang/phobos/pull/4318) * or compile time is slowed down a lot (as I showed in my original post, via import(__FILE__)[__LINE__] + redoing the work the compiler already did) This proposal is simple to implement, useful, and exists in other languages (C++ and many others)
