Re: SoCal Code Camp
It went well. Contracts were the feature that most interested people.
I'll post the slides some time this week.

Re: SoCal Code Camp
Contracts....Few Years ago i spoke about contracts and someone from a "very large" company said that TDD is the future, no reason to develop contracts in languags.... today contracts are really appreciate and C# 4.0, for example, will include something like that. Good shot, Chuck,

Re: SoCal Code Camp
Thanks. I really like having both available. And one of the nice things about contracts is that they execute every time a method is invoked. So those conditions are getting tested throughout the lifetime of your program every time that method is used.
Sometimes I find it hard to describe the behavior of a method with contracts, in which case it becomes really handy to be able to write "test" and just code up some examples.

Here are the slides: Cobra-SoCal-Code-Camp-2009-01-Slides.pdf
In general, the docs page at http://cobra-language.com/docs/ has a link to the latest slides.

Thanks. About the "implementing units" part, one alluring possibility is that Cobra takes the C++ route:
http://stackoverflow.com/questions/2378 ... more-bloat
Consider:
extend double
cue suffix "cm" (value_in_cm as double) as double is shared # Note that this would require shared
# extension methods, which are not in C#
return value_in_cm * 0.01
extend int
cue suffix "b" (str as String) as int is shared # Raw version, gives us access to the string
# that originated the literal
return CobraCore.convertBinToInt(str)
class Rational
# ... rest of implementation ...
cue suffix "r" (num as double) as Rational is shared
return Rational(num, 1)
class Foo
def main is shared
x = 3cm # equivalent to double.suffix "cm" (3)
print x # 0.03
i = 1000100001101b # eq. to i = int.suffix "b"("1000100001101")
print i # whatever that sequence of bits means in base-10
a = 1 / 3r # eq. to a = 1 / Rational.suffix "r" (3)
print a # Rational [1 / 3]
The "b" suffix could be part of the standard library, as well as other obvious choices such as the "i" suffix for imaginary literals.

Re: SoCal Code Camp
Interesting stuff here. Although I'm interested in units of measurement, I won't take a real look at them until after Cobra 0.9. However, I've started ticket:144 where we can collect information and ideas in the mean time. Added a link back to this discussion, for example.
Cobra 0.9 is described at http://cobra-language.com/trac/cobra/roadmap where you can also click on "active tickets" to see what's left.

I agree that this is low priority. After all, it's taken +25 years for this feature to make its way into C++!
