800cb006e7* Change `styleCheck` to ignore foreign packages * Symbols from foreign packages are now ignored. * Fixed `styleCheck` violations in `compiler` package. * Added symbol ownership to custom annotation pragmas. * Minor refactors to cleanup style check callsites. * Minor internal documentation of reasons why a symbol isn't checked. Style violations were fixed in the compiler after thet were exposed by the changes. The compiler wouldn't compile otherwise. Symbol ownership for custom pragma annotations is needed for checking the annotation's style. A NPE was raised otherwise. Fixes #10201 See also nim-lang/RFCs#456 * Fix a misunderstanding about excluding field style checks I had refactored the callsites of `styleCheckUse` to apply the DRY principle, but I misunderstood the field access handling in a template as a general case. This corrects it. * Fix some `styleCheck` violations in `compiler/evalffi` The violations were exposed in CI when the compiler was built with libffi. * Removed some uneeded transitionary code * Add changelog entry Co-authored-by: quantimnot <quantimnot@users.noreply.github.com>

# This module contains a word recognizer, i.e. a simple
|
|
# procedure which maps special words to an enumeration.
|
|
# It is primarily needed because Pascal's case statement
|
|
# does not support strings. Without this the code would
|
|
# be slow and unreadable.
