What do you think about it, can we have something similar to that.

Maybe something like this:


int func() return 5;

with(auto x = func()) if (condition(x))
    do_something_with(x);
else
    do_something_else_with(x);

this would be rewrite to

int func() return 5;

{
    auto x = func();
    if (condition(x))
        do_something_with(x);
    else
        do_something_else_with(x);
}
