Yes, this is helpful. But also one of the things we need is a way so that we can have "additional input" -- i.e., when entering constructs that span multiple lines, for the language to be able to signal HLLCompiler to obtain additional lines of input. > (a possible improvement would be to have an array > of prompts; many languages have 2 prompts, when a "\" or whatever is > given.

I think we need to go ahead and have it possible to use an array of prompts. > As an example, I used this in Pynie.pir, which prints nicely: > > C:\parrot\languages\pynie>..\..\parrot pynie.pbc > Python 2.5 for Parrot > Type "help", "copyright", "credits" or "license" for more information. > >>> I'm generally in favor of not making false promises. So, don't offer options that aren't available. :-) Similarly, Pynie was modeled on Python 2.3, not 2.5... but if someone has a copy of Python's 2.5 specification (or can point me to it on the web), we can do 2.5.
