Scope modifiers: Difference between revisions

The stars around <code>*bug*</code> are called "earmuffs" and are not a special syntax. Rather, they are part of the symbol's name. This widely-used convention effectively places dynamic variables into their own namespace, which is necessary for preventing bugs. Common Lisp itself follows this tradition in its standard dynamic variables like <code>*print-circle*</code>, <code>*readtable*</code> et cetera.
