[edit] *calling-env*

This is the environment of the caller. For instance, the following expression would show the foo of the caller:

(el *calling-env* &foo)

[edit] *current-condition*

The current condition, if a condition is being handled.

See: Conditions

[edit] *debug*

Setting *debug* makes the interpreter run in debug mode.

1. Tail recursion no longer occurs, making stack traces more comprehensible.
2. Debugging hooks are called.

[edit] *env*

The current environment.

[edit] *global-env*

The top-level environment.

[edit] *signal-handler*

The signal handler. You'll need to override this with your own unless you like the default behavior.

See Conditions

[edit] *stack*

This is the actual stack. Although you cannot push new items on the stack or modify existing items, you can remove items. You may also replace the stack.

(TODO: May allow stack frames to be moved between stacks, and perhaps the creation of stack frames.)
