# Suppress Rules:
# - v530: The return value of function 'release_value' is required to be utilized.
# Our TRY(..) macro seems to breaks this rule and trigger weird behavior in PVS Studio.
#
# - v677: Custom declaration of a standard '<example>' type. The declaration from system header files should be used instead.
# This rule doesn't make sense for Serenity, as we are the system headers.
#
# - v1061: Extending the 'std' namespace may result in undefined behavior.
# We have no choice, some features of C++ require us to.
#
# - V1052: Declaring virtual methods in a class marked as 'final' is pointless.
# This rule contradicts the serenity style rules.
#
# - False Positives:
# v591: Non-void function should return a value.
# v603: Object was created but is not being used.
# v1047: Lifetime of the lambda is greater than lifetime of the local variable captured by reference.
# v1076: Code contains invisible characters that may alter its logic.
