This is a variation on #13639.
"Control-flow declarations" were formerly called "if-var" and "while-var", introduced in #17047 and #17304.
Right now control-flow declarations accept expressions only of class types. This issue asks whether we want to generalize them to all types that can be used in conditionals. For example:
if const i = someIntegerFunction() {
// here 'i' is non-0
}
