@@ -823,3 +823,14 @@ operations on a given component, you MAY want to override or wrap around
the
`component-if-feature`
method for that component instead of defining
all those
`perform`
,
`output-files`
and
`input-files`
methods.
## Other
Do not side-effect the current
`*readtable*`
,
which is never guaranteed to be writable, and
may not be what is current when you need the modification.
If you need modifications to the readtable, use
`named-readtables`
,
`reader-interception`
, or some other adequate mechanism.
To bind the readtable, use
`named-readtables:in-readtable`
or
`cl-syntax:in-syntax`
in each file that needs a non-standard readtable, and/or use an
`:around-compile`
hook
to automatically bind it around every file in a module or system.
