https://issues.dlang.org/show_bug.cgi?id=19461 Issue ID: 19461 Summary: Function literals can't be extern(C) Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: enhancement Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: atila.neves gmail.com https://dlang.org/spec/expression.html#function_literals Unfortunately, they can't be extern(C), and if attempted there is no compiler or linker error to warn the user about the ABI incompatilibity. Using the parameters just won't work and there's no way to fix it. This shows up in, say, attempting to use function literals as the function pointer value for a Python extension implemented in D. An extern(C) function has to be written/generated just to fix the ABI of calling it. --
