When was the last time you created an XML document to have zero elements? Such a document is not well-formed. - Many programming languages do not This works in C, at least as implemented by gcc 4.8.1. Turning on -Wall -pedantic triggers a warning. It's useless, anyway. - Many programming languages do not This also works in gcc 4.8.1. Turning on -Wall -pedantic tells us that the zero-size array violates ISO C but is permitted as a gcc extension.
- Many programming languages do not This triggers a gcc warning by default, as it is useless, but it works. - In some programming languages the I'm not familiar with any languages that make this mandatory. In Algol 68 it's *possible* to call a procedure with no parameters without using (), but this is a type coercion from (say) "proc-returning-int" to "int".
- Many compilers refuse to compile a This works by default in gcc, but -Wall -pedantic again says that ISO C forbids it, probably because of its uselessness.
