PHP joins the untyped-receiver languages for the unique-name method guess:
`$x->m()` takes the one project method named `m` only when the receiver
shares a word with its owner, or names a class (the whole name, or its last
camel word: `$newRole` → Role) whose ancestry — extends + trait `use`,
namespace-aware — has the method.
A/B (edges removed / added): guzzle -359, BookStack -302, console -124,
Slim -124, monica -53. Removals are PSR-7 / framework / exception calls
bound to a test double or unrelated helper; the deliberate loss is calls
through receivers named after neither (`$loaner->loansAsLoaner()`).
