phan/phan 2.7.1

Release 2.7.1 supporting PHP 7.0-7.4 syntax

on PHP Packagist

New features(CLI, Configs):

• Improve the output of tool/make_stubs. Use better defaults than null.
  Render unknown for unknown defaults in tool/make_stubs and Phan's issue messages.
  (default is a reserved keyword used in switch statements)

Bug Fixes:

• Work around unintentionally using symfony/polyfill-72 for spl_object_id instead of Phan's polyfill.
  The version used caused issues on 32-bit php 7.1 installations, and a slight slowdown in php 7.1.

Plugins:

• PHP 8.0-dev compatibility fixes for InvokePHPNativeSyntaxCheckPlugin on Windows.
• Infer that some new functions in PHP 8.0-dev should be used in UseReturnValuePlugin
• Emit the line and expression of the duplicated array key or switch case (#3837)
