Today I have finished implementing 90% of primitive operators; Pugs can now evaluate most simple expressions, including junctive autothreading and magical/infinite ranges. Their implementation are in:
http://wagner.elixus.org/~autrijus/darcs/pugs/Prim.hs
As such, there are some corner cases I couldn't find in the spec; please
correct me if my treatment is wrong:
* What is the value of a pair in numeric context? in string context?
Currently I'm taking the ".value" part as its value.
* What is the value of a reference in any of the scalar contexts?
Currently I'm blindly dereferencing it.
* How many bits are "+^" operating on?
Currently it is using a native Unsigned Int.
* Does "**" flatten recursively?
Currently it only flattens the first level of the list.
* Does "(3&0) and (4|0)" evaluate to "(3&0)" or "False"?
Currently it evaluates to "(3&0)".
Thanks,
