If we left semicolons more than one instruction per line will be allowed.
What about ++, --, += etc., operators overload and such c stuff?

Agreed about the semicolon. Especially since the source are in eol
terminator members. In other words, finding the end of the line isn't hard
at all. A Semicolon shouldn't be needed.
As for the GOTOs, I'm happy to see them gone.
If we must have semicolons, I'd also like to see the use of curly brackets.
Just for the heckuv it.
if (x=1) {
do this
and this
andi this
}
