> Any defined-but-non-coderef value is stringified

Correction: any "non-coderef value is stringified" , even undef is stringified to an empty string. ( It's just tricky to create a sub for an empty symbol. :)

  DB<199> $obj = bless {},"tmp"

  DB<200> $tmp::{''} = sub { say "empty" }

  DB<201> $meth = undef

  DB<202> $obj->$meth
empty

  DB<203>
