Description

App is stuck when I try to call this.$t(...) from within a mixin.

When I inspect this context from the mixin I see this on $t object for arguments and caller:

Exception: TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them at Function.remoteFunction (<anonymous>:2:14)

I'm using the latest version (8.2.1)

Research direction
Investigate vue i18n's $t implementation, particularly how it handles context in mixins. The error indicates strict mode issues with 'caller', 'callee', 'arguments'. Check the source file for $t to see how it references 'this' and whether any workaround exists (e.g., using a function reference). Look at related issues or comments for any suggested solutions.
