In general Raku tries to avoid special cases... so I think that braces pretty much _always_ introduce a new scope. I can't think of any exceptions at the moment, except for *maybe* when they are used as a hash constructor. (And perhaps not even there.) Of course I could be mistaken in this... but as a general rule, in language design there's been an effort to keep things consistent so that we don't have to say things like "braces create a new scope except when used in string interpolation" etc. Pm
