## Package/File Information

No package provided/required
Filename: xotcl/library/lib/upvarcompat.xotcl

Description: | Provide a version of upvar and uplevel that provide backward compatibility such that these commands ignore inactive filter and mixin frames (upvar behaves the same whether or not a filter is installed). Newer scripts should use `upvar/uplevel [self callinglevel] var/command` instead.
