Jeff answered the Unicode/str part, so I'll answer the following code part.
Ultimately these come from the properties in Builtin.cs:
public static PythonType unicode {
get {
return DynamicHelpers.GetPythonTypeFromType(typeof(string));
}
}
public static PythonType str {
get {
return DynamicHelpers.GetPythonTypeFromType(typeof(string));
}
}
Ultimately we produce a PythonModule which has a PythonDictionary. All of our
dictionaries have a storage class which abstracts way how the dictionary is
actually implemented. For built-in modules we have a ModuleDictionaryStorage
object. The ModuleDictionaryStorage lazily reflects over the module type and
caches the result. For properties it'll pull the value out the first time it's
accessed.

Subject: [Ironpython-users] type for unicode and str
Hi All,
I was just playing with unicode strings and I notice a difference with CPython
and IronPython. On CPython 2.7.2 I get the following
>>> type(u"A")
<type 'unicode'>
>>> type("A")
<type 'str'>
On Ironpython the latest 2.7.2 Alpha 1 I get the following
>>> type(u"A")
<type 'str'>
>>> type("A")
<type 'str'>
I decided to crack open the source and see where this type function is defined.
I followed to the builtin.cs with the PythonModule but I got kind lost there.
If anyone can provide some helpful hints that would be great.
Thanks
Danny
