[Mono-list] python scripting

[A Rafael D Teixeira]

You can also work from inside our mcs compiler suite, one of the things I 
intend to do with MonoBASIC is to "pythonize" a bit, get also some things 
from Ruby (things like adding methods to instances of a class instead of 
classes), but while that is good exercise most Python programmers would like 
to have a good implementation of their language.

The problem with ActiveState approach is that they are running a standalone 
python or perl interpreter, that is encapsulated in COM and called using 
.NET Interop Services (COM Wrapping). The good thing in their approach is 
they can have 100% percent python/perl syntax and types and interpretative 
power, but at a cost of a lot of overhead in the wrapping layers.

In MonoBASIC Iīll try to expand VB.NET a lot, but Iīll keep generating true 
.NET objects, that may have behind-the-scene calls to libraries of 
higher-level functionality.

The problem I see with implementing a perl/python syntax in Mono/.Net is 
about choosing between a true interpreter that may have performance problems 
or a compiler with perhaps a altered syntax to mandate strict type checking.

I donīt know a lot about Microsoftīs JScript.NET, only that itīs untyped, 
but they deemphasize it a lot in the documentation, an my expectation is 
that it is probably a bad performer.
