in thread Shouldn't LITERAL references be readonly? (updated)

you are aware that "constructor" isn't even mentioned in your definition? ;)

calling [$a] a "literal constructor" is not far fetched.

a non literal construction is in contrast to do { @a=($a); \@a } because it involves a variable.

This it meets the definitions in perlglossary ("no variable") and is also mirrored in JS terminology which has 100% the same semantic.

    Yes, that is what I misremembered: perlref calls them "composers" but they act just like constructors. :-)

    Calling it a "constructor" is a hint that it does something at runtime, instead of being a literal embedded into the program text. That its return value is mutable should not be a surprise.
