Q: What is the difference between a neurotic and a psychotic?
A: A psychotic really thinks 2+2 = 5
A neurotic knows 2+2 = 4, but just can't stand it. ;^)
I really can't stand some of the oddities of Complex numbers in Squeak

Hi guys
What I would love is the following: that we get a good Complex package!
Since we can do method extensions in Smalltalk we can design a really
nice Complex
packages with its own tests.
We could publish for now Complex into PharoTaskForces or create a
PharoExternalPackages
or whatever.

Ken,The desired behavior appears to be that -1 sqrt raises an error regardless of the complex package; -1 asComplex sqrt works when the package is installed. Sig, is that a fair statement of your position?Bill -Origin
I don't want to seem I turned the rant mode, on, but:
Last statement makes so little sense as saying the "expected" thing is that
4 sqrt
should return a tuple #(2.0 -2.0) because it happened before we had computers
The "Principle of Least Surprise" should be taken in the context of the Smalltal
