Hi,

I wonder is it is possible to remove a constant at runtime. We can
create a constant with "const_set", is there any functions which will
allows us to remove or delete a constant?

Thanks you very much

Look at Module#remove_const that may do what you want.

---------------------------------------------------------------------------------
remove_const(sym) => obj
---------------------------------------------------------------------------------
Removes the definition of the given constant, returning that constant's
value. Predefined classes and singleton objects (such as true) cannot
be removed.
