True enough. Either one of these would be more clear than the
original example in terms of user intent.
As well, isn't there a way to escape a character that would otherwise
be interpolated? If the intent were as you suppose, the original
could be rewritten as:
$ perl6 -e 'my $foo = "foo";say "\{" ~ $foo ~ "}"'
(Or would you need to escape the closing curly brace as well as the
opening one?)
