Summary: Same method object does not yield equal with = or == 

Initial Comment:
Retrieving the same method object from the .Object class, one time with 'isA' and one time with 'isInstanceOf' and then comparing the two references (which create the same hash value if sending '==' to them) does not yield .true. Testing for unequality wrongly returns .false.

Here is a test program:

------------ cut here -----------
m1=.object~method("isA")
m2=.object~method("isInstanceOf")

say "m1     :" m1~string '@' m1~"=="~c2x
say "m2     :" m2~string '@' m2~"=="~c2x
say

say "m1=m2  :" (m1=m2)
say "m1==m2 :" (m1==m2)
say

say "m1<>m2 :" (m1<>m2)
say "m1><m2 :" (m1><m2)
say

say "m1\=m2 :" (m1\=m2)
say "m1\==m2:" (m1\==m2)
say

say "-------"
say "now using the method's hash values:"

say
say "m1~'==' =   m2~'==' :" (m1~'==' = m2~'==')
say "m1~'==' ==  m2~'==' :" (m1~'==' == m2~'==')

say
say "m1~'==' <>  m2~'==' :" (m1~'==' <> m2~'==')
say "m1~'==' ><  m2~'==' :" (m1~'==' >< m2~'==')
say

say "m1~'==' \=  m2~'==' :" (m1~'==' \=  m2~'==')
say "m1~'==' \== m2~'==' :" (m1~'==' \== m2~'==')
------------ cut here -----------

Running the program under 

------------ cut here -----------
m1     : a Method @ 19000104
m2     : a Method @ 19000104

m1=m2  : 0
m1==m2 : 0

m1<>m2 : 1
m1><m2 : 1

m1\=m2 : 1
m1\==m2: 1

-------
now using the method's hash values:

m1~'==' =   m2~'==' : 1
m1~'==' ==  m2~'==' : 1

m1~'==' <>  m2~'==' : 0
m1~'==' ><  m2~'==' : 0

m1~'==' \=  m2~'==' : 0
m1~'==' \== m2~'==' : 0
------------ cut here -----------

These are not the same method object, so they should not be expected to
compare equal.
