* Null pointers check doesn't work for methods:
"
class Main {
void main() {
A a;
a.m();
}
}
class A {
void m() { }
}
"
* Side effects
If methods have side effects, then the execution order matters:
"
class Main {
void main() {
write(m1() + m2());
writeln();
}
int m1() {
write(1);
return 1;
}
int m2() {
write(2);
return 2;
}
}
"
* Can't compile programs which use many registers
