That is, they are obviously legal in initializer lists.
All compilers that I tried reject trailing comma in function calls.But is it (rejection) really required by the Standard? I don't know.>
Yes. The syntax (in 6.5.2p1) is :
Yes, but also no.
A trailing comma in an argument list in a function call is a syntax
error, but the standard doesn't require syntax errors (or constraint
violations) to be fatal. Rejection is required only for #error.
In most cases, most compilers do treat syntax errors as fatal, but for
example a compiler that accepts trailing commas as an extension might
produce a non-fatal warning even in conforming mode.
