Confusing error caused by `return` without a semicolon

[dbohdan]

Compiling the following code results in this error: "Assertion failed! Aborting."

module ret;

void main() {
    return
}

The problem with the code is that the semicolon is missing after the return statement, which does not have an argument. The code compiles without the semicolon when return has an argument.

// Compiles.
module ret;

int main() {
    return 0
}

The compiler should say the error is due to invalid syntax.

Edit: Oops, I misdiagnosed the cause of the error at first. Fixed.

Thanks! Fixed.

It's a bit weird to parse because return is an expression, not a statement.

Error message is now:

hello.nt:3:
void main() { return }
                     ^ expression or semicolon expected
