So, it actually should also make a copy of pragmas.
Yes. pragmas are effectively referenced from literals. �If a method needs ti the penultimate literal (which otherwise is the method;s selector) holds an AdditionalMethodState which refers back to its method. �This needs to be copied if one is copying a method, since the backpointer needs to refer to the owning method, not the method form which the copy was made.

if you tell more, why #copy is not enough for you.
If literals are read-only (and Array/ByteArray/String/Float literals are conceptually read-only but not actually) you don't need to make a deep copy. �You only need to copy the AdditionalMethodState, if present, and the class association, if you want to install the method somewhere else.
