The ASC Is a Map of the ASC.

A big part of what the way this all works is the for let's say you're your compilers compiling a namespace right. And it's going through form by form usually functions and that ultimately ends up producing a huge map of information. It wants to basically cash that information and reread it back in from disk so that it can later on without having to recompile it each time. Such as a pragmatic thing that it's doing. All that gets saved it gets cached to disk. You'll know with with this stuff it's the compiler analysis metadata that gets written out. That's all the product of the analyzer.
