I still don't know where to find documentation for "is" (which I just
found out in another forum post is overloaded for dynamic arrays).
Can users overload the meaning of "is" themselves?
Here you find info on the D language:
http://dlang.org/spec.html
"is" is an operator, so it's an expression, so you find it here:

I don't see where it talks about how to compare dynamic arrays with
"is". It says:
The forms of the IsExpression are:
1. is ( Type )
...
2. is ( Type : TypeSpecialization )
...
3. is ( Type == TypeSpecialization )
...
4. is ( Type Identifier )
...
5. is ( Type Identifier : TypeSpecialization )
...
6. is ( Type Identifier == TypeSpecialization )
...
7. is ( Type : TypeSpecialization , TemplateParameterList )
is ( Type == TypeSpecialization , TemplateParameterList )
is ( Type Identifier : TypeSpecialization , TemplateParameterList )
is ( Type Identifier == TypeSpecialization , TemplateParameterList )
...
This doesn't explain "a is b" where a and b are both dynamic arrays.
`a is b` is called the "Identity expressions" and is very different from
the "is expression".
