hehe, that's funny. Díd you use ILASM to create that?
No, Boo DSL based on XML storage.
Freaky stuff
Yeah, sorta the basis of much obfuscation software: just rename members to use something in the Unicode set that C#/VB/etc doesn't support...
I wonder if that were part of the changes for the C++/CLR version, where has things like "for each" being a single keyword.
Why are you specifying an hour value in hex?
That is a Reflector setting
Hmm, it is surprising that they allow that.
Yes, this ability of CLR to grok names with whitespaces is used for a long time by Nemerle guys in their unit-testing DSL (their site seems to be down but contents can be found in google cache, for example).

Do you have a feed for the comments on your blog Oren?
Andres,
Not that I know of.
If SubText has it, then probably
That's nice is there any way to call it from C#?
Not really, no.
VB probably can, though
You can also call it by C# code, just use something like administrators\u0020can\u0020always\u0020login. C# allows unicode escapes in identifier names. See the language specification ECMA-334, section 9.4.2 Identifiers. This is a valid example from this section:
class @class
{
public static void @static(bool @bool) {
if (@bool)
System.Console.WriteLine("true");
else
System.Console.WriteLine("false");
}
}
class Class1
{
static void M() {
cl\u0061ss.st\u0061tic(true);
}
}
Thomas,
Thanks, it is good to know.
Scary as hell, too.
