Hello all,
Is there a C++ standard proposal for named parameter addition?
I am looking for an "N-paper" for named parameters similar to N2081 for concepts, or N1962 for contracts.
named parameters were rejected years ago.
They were raised and dropped, but that doesn't mean they can't come back.
Yes, from "Design and Evolution of C++" Section 6.5.1: << Roland Hartinger's proposal for keyword arguments, that is, for a mechanism for specifying arguments by name in a call, was close to technically perfect. The reason the proposal was withdrawn rather than accepted is therefore particularly interesting... >> Does anyone have a reference to the actual proposal from Roland Hartinger? (I could not find it on the Internet...) BTW, the reason I am asking is because I would like to compare notes on named parameters between the dropped C++ proposal, Boost.Parameter, and Boost.Contract syntactical wrappers around Boost.Parameter. For example, from reading "Design and Evolution of C++" section 6.5.1, the dropped C++ proposal did not include type requirements which are instead supported by Boost.Parameter (and therefore by Boost.Contract). I am curious about any other difference. Thanks a lot. -- Lorenzo
