I simply can’t see changing the syntax of such a fundamental construct,
especially when a suitable replacement, which accomplishes your desired goal of
introducing no new variables outside (visually) of a pair of curly braces,
already exists. The language’s development is well past the stage of the
cosmetics of basic syntax.
