On: C++ Modules Might Be Dead-On-Arrival

[haberman]

I get that, but there's also precedent for cutting ancient things loose. Both C and C++ have finally decided to specify that signed integers are two's complement: https://twitter.com/jfbastien/status/989242576598327296?lang... Also trigraphs are gone in C++17.

This C++ code actually compiles with clang++. Incredible!

    int main(int argc, char *argv<::>)
    <%
        if (argc not_eq 1 and argc not_eq 2) <% return 1; %>
        return 0;
    %>

Digraphs are still a part of the language. I would be more surprised if a conformant piece of code did not compile with a conformant compiler.

Trigraphs are gone, but it took a while to win IBM representatives over it

[favorited → pjmlp]

I don't think they were ever really won over, I think their concerns were heard and they begrudgingly acquiesced rather than vote down C++17.
