Making a variable "unspecial"

Hello,

Is there an (undocumented?) way to make a special variable "unspecial"
again?

Some other Lisps allow doing this. The Maxima Computer Algebra System does
this because some source code files use a certain variable as a special
one, while others don't. I'm aware that this is not good practice,
especially since the special variables are not named like *var*, but just
like var.

Accessing special variables is more expensive than accessing lexical ones.

Best regards
David Scherfgen
