Hi,
The function {name}:operator has a strange behavior if it is called
with a symbol that is not the name of an operator:
? (setq formalism ({name}:formalism 'Glider))
Glider : tables read.
= #<formalism Glider>
? ({name}:operator 'coco formalism)
***** Fatal error : no room for lists.
What is the correct way to test whether an operator with a given name
exists or not in a formalism??
