"Internal`" context is one of the core contexts that Mathematica uses. It's got no targeted focus, but rather appears to be a place where developers dump the cruft they don't know what to do with.
Provides a general purpose container that has efficient push and pop behavior. Especially useful in
Allows for a setup block that will be evaluated before a code block and a tear-down block that will evaluate no matter what errors are raised in the code block . This is highly-useful for error handling.
GeneralUtilities`SetupTeardown provides a mild generalization on this.
Allows for definitions to be preserved, but otherwise uses
Block semantics. Very useful for metaprogramming and overloading.
This is a tricky function that tells the kernel to preserve some amount of old-state for efficiency/control reasons.
This just makes a nicely formatted panel with a 9-patch
A system of internal handlers for various events that occur. Generally best used with
This acts in much the same way to the handlers, but can treat them in a
Block -like fashion.
Block but can localize some non-
