126.96.36.199.2 Naming of Compiler Macros
Compiler macros may be defined for function names that name
macros as well as functions.
Compiler macro definitions are strictly global. There is no provision
for defining local compiler macros in the way that macrolet
defines local macros. Lexical bindings of a function name shadow any
compiler macro definition associated with the name as well as its
global function or macro definition.
Note that the presence of a compiler macro definition does not affect
the values returned by
functions that access function definitions (e.g., fboundp)
or macro definitions (e.g., macroexpand).
Compiler macros are global, and the function
compiler-macro-function is sufficient to resolve their interaction
with other lexical and global definitions.
