* Add failing test * Add visitor to soup up classlike references * Move a whole bunch of code into the visitor * Move some methods back, move onto analysis stage * Use the getAliases method everywhere * Fix refs * Fix more refs * Fix some tests * Fix more tests * Fix include tests * Shift config class finding to project checker and fix bugs * Fix a few more tests * transition test to new syntax * Remove var_dump * Delete a bunch of code and fix mutation test * Remove unnecessary visitation * Transition to better mocked out file provider, breaking some cached statement loading * Use different scheme for naming anonymous classes * Fix anonymous class issues * Refactor file/statement loading * Add specific property types * Fix mapped property assignment * Improve how we deal with traits * Fix trait checking * Pass Psalm checks * Add multi-process support * Delay console output until the end * Remove PHP 7 syntax * Update file storage with classes * Fix scanning individual files and add reflection return types * Always turn XDebug off * Add quicker method of getting method mutations * Queue return types for crawling * Interpret all strings as possible classes once we see a `get_class` call * Check invalid return types again * Fix template namespacing issues * Default to class-insensitive file names for includes * Don’t overwrite existing issues data * Add var docblocks for scanning * Add null check * Fix loading of external classes in templates * Only try to populate class when we haven’t yet seen it’s not a class * Fix trait property accessibility * Only ever improve docblock param type * Make param replacement more robust * Fix static const missing inferred type * Fix a few more tests * Register constant definitions * Fix trait aliasing * Skip constant type tests for now * Fix linting issues * Make sure caching is off for tests * Remove unnecessary return * Use emulative parser if on PHP 5.6 * Cache parser for faster first-time parse * Fix constant resolution when scanning classes * Remove test that’s beyond a practical scope * Add back --diff support * Add --help for --threads * Remove unused vars
