SID scopes:

There are only two scopes, local and global.

Global scope:

The global scope is the root of all source files and is accessible from everywhere in the program. It can only be written to from the root of a source file and due to the way it could otherwise cause race conditions evaluation in the root of source files is strictly sequential and blocking.

Local scope:

The local scope exists in every function and by default has definitions for the function's arguments. If local scope has a definition overlapping with one in global scope the local scope has priority.

Writing to scope:

The def function can be used to define values into current scope. Defining the same value into scope multiple times is only allowed if in a sequentially executing scope (either the root scope or a function with a list of operations).

In the long term usage of the defined value will be automatically registered as a dependence and scheduling in set functions will ensure that the definition is done before any usage of it.
