Another thing that I often do is switch on an expression, but I often

a problem where, within the scope, I have no way to refer to the result

This is particularly important when range cases appear.
switch(x+10)
{
case 10: .. case 20:
// what is the value?
}
Obviously then I need to do this:
auto y = x+10;
switch(y)
{
case 10: .. case 20:
// I know y...
}
But this is a bit lame. I'm polluting the outer namespace, and wasting a
line.
I wonder if a variable declaration could be made possible in the switch:
switch(y = x+10) // obviously implicitly auto, like in foreach
{
case 10: .. case 20:
// I have y, no pollution of the outer scope, no wasted line. yay!
}
for and foreach can both declare variables this way... does it make sense
here? Useful?
Yes, this would be good. I bet bearophile has an enhancement request
already ;)
