# Core error logging is built up of a chain containing:
# - A top level \ErrorHandler which registers the error service
# - A \Logger which acts as the error service
# - A \HandlerInterface which handles errors for the logger
# - One or more \FormatterInterface which format errors for the handler
#
# Logging for use outside of core error handling also uses the same implementations,
# but is available without the HandlerInterfaces attached

    calls:
      pushDefaultLogger: [ pushLogger, [ '%$Psr\Log\LoggerInterface' ] ]
      pushErrorHandler: [ pushLogger, [ '%$Psr\Log\LoggerInterface.errorhandler' ] ]

  # Default implementation for use as a standard logger. Up to developers to attach their own
  # handlers
