Ah, that's also ok. But then you have to remember to use myVar
instead of var.
I have wanted to remove a variable from scope before. I think it
would be kinda cool if we could do something like __undefine(x),
and subsequent uses of it would be an error. (It could also
prohibit redeclaration of it if we wanted.)
D doesn't have that, but we can get reasonably close using other
functions when we change param types (just forward it to the
other overload) and functions and/or scopes for local variables:
void foo() {
{ int a; /* use a */ }
// a is now gone, so you don't accidentally use it later in
the function
}
