Unrelated to this CL, but something that I notice:

In some places we treat "tryjob" as one word, and in some places we treat it as
two words (e.g. the name of this class, and on line 22 below, and in the name of
this file).

In the official documentation, it's treated as two words ("try job").

Done.
