- The name prefilter checks a case-SENSITIVE set of known names, so in PHP,
Pascal, CFML, COBOL and VB.NET — whose identifiers ignore case — a call
written in another case (`formatprice()` for `FormatPrice`, TestBox's
`ToMatchWithCase()`) was dropped before any strategy ran. Those languages
now also check a lowercase set (built lazily, only when asked).
- `isBarePhpCall` took any `>` before a name for `->`: every call after `=>`
in a PHP array (`'total' => count($items)`, `'by' => user()->id`,
`'label' => trans('…')`) was a member call, and found a same-named method
— 166 wrong edges on BookStack (`trans` → LocaleDefinition::trans,
`new Response` → ImageStorageDisk::response, `url()`, `config()`, `count()`).
It now requires `->` / `?->` / `::`.
- A fuzzy `instantiates` never names a method.
