I want to know exactly what is considered to be 'throw'.
I'm able to use dynamic arrays (which can throw 'Range

asserts in a nothrow function. Shouldn't those be considered
'throw'?
Yes, the documentation is minimal: :)
http://dlang.org/function.html#nothrow-functions
It says "Nothrow functions do not throw any exceptions derived
from class Exception."
I have more information here but the language is misleading:
http://ddili.org/ders/d.en/functions_more.html#ix_functions_more.nothrow
I am going to add something like the following to clarify:
"Note: Remember that it is not recommended to catch Error nor
its base class Throwable. What I mean by "any exception" here
is "any exception that is defined under the Exception
hierarchy." A nothrow function can still emit exceptions that
are under the Error hierarchy, which represents irrecoverable
error conditions that should preclude the program from
continuing its execution."
In other words, nothrow means "does not emit Exception, it can
still emit Error."

Thanks, that clear things up.
