Unless it's a typo, the quote is clearly specified in the singular context i.e. 'bareword identifier' & 'it' (c/w 'bareword identifier
s') - thus the compiler is behaving according to spec. and invalidating what appears to be a bareword list.
I wonder if it's down to the single quoting, by the compiler, of single barewords within braces i.e. a hash key context consider the following 2 equivalent statements: $hash{key} = 'some val'; & $hash{'key'} = 'some val'; - equivalent since the single quotes around the key, in the former, are inserted (if not already there) by the compiler.
As we all know, the compiler doesn't do any auto-quoting of list values (if not already quoted) - because it [the compiler] doesn't (and can't??) 2nd guess what the author intended - hence the behaviour is entirely both determinstic & consistent.
