patch platform 562 subclassing basic number types fails to
inherit basic ops like add, sub, mul and div bsdz kjs "When
subclassing base types like Integer, Float and Complex. The ops
sub, add, mul and div are not properly inherited by the derived
class. A basic example is provided by the following code: - {{{
.sub '' :main $P0 = subclass 'Integer', 'FooInt' print 'Integer:
10 - 1 = ' $P0 = new 'Integer' $P0 = 10 sub $P1, $P0, 1 say $P1
print 'FooInt: 10 - 1 = ' $P0 = new 'FooInt' $P0 = 10 #$P1 = new
'FooInt' # uncommenting here does not help sub $P1, $P0, 1 say
$P1 .end }}} outputs the following: - {{{ Integer: 10 - 1 = 9
FooInt: 10 - 1 = Multiple Dispatch: No suitable candidate found
for 'subtract_int', with signature 'PIP->P' ... }}} This appears
to be related to RT which outlines the problem for a specific
case of a Complex type. The attached script proves the bug also
affects add, su
