Hi, I don't like this kind of "polymorphism" (perhaps because being a C++
hacker) where knowledge about the types is spreaded to other functions. It
would be much cooler to add operator - to the make object! part of
complex!. Than whenever a - operator is used Rebol should see if one is
defined (wouldn't it be possible to define a function -?)
Like:
complex!: make object! [
re: 0
im: 0
-: func[value1 [complex!] value2 [complex!]][
return make complex! [
re: value1/re - value2/re
im: value1/im - value2/im
]
]
]
This would be really nice.
