Version 1.8.4                                    Mon Sep 25 2023                              msymbol_put(3m17n)

       Set the value of a symbol property. The msymbol_put() function assigns val to the value of the symbol
       property that belongs to symbol and whose key is key. If the symbol property already has a value, val
       overwrites the old one. Both symbol and key must not be Mnil.

       If key is a managing key, val must be a managed object. In this case, the reference count of the old
       value, if not NULL, is decremented by one, and that of val is incremented by one.
