Description:
#3424 added support for the
reserved
mangle option which prevents identifiers from being mangled when listed in the array. This is fine in most cases but can cause issues when the compressor brings two reserved variables into the same scope. When this occurs the generated code results in a parsing error due to the duplicate identifier.This PR adds a test to cover this case and a proposed fix by ignoring reserved identifiers for patterns and expressions.
