... NOT set(range(x)). There's no literal for an empty set; use set() (or {1}&{2} :-). There's no frozenset literal; they are too rarely needed."

How can I repeat a character in Bash?
...
No easy way. But for example:
seq -s= 100|tr -d '[:digit:]'
Or maybe a standard-conforming way:

Default value to a parameter while passing by reference in C++
...use an actual instance as the default:
static int AVAL = 1;
void f( int & x = AVAL ) {
// stuff
}
int main() {
f(); // equivalent to f(AVAL);
}
but this is of very limited practical use.
