The old code for some reason assumed that the length of the command
would be 1. This is because when I tested this I would use single
letter command names and it would "just work" when in reality it was
completely incorrect.
A reminder to thoroughly test instead of just fitting something to work
Context.reinvoke would be the new way to bypass checks and cooldowns.
However, with its addition comes a change in the invocation order of
checks, callbacks, and cooldowns. While previously cooldowns would
trigger after command argument parsing, the new behaviour parses
cooldowns before command argument parsing.
The implication of this change is that Context.args and Context.kwargs
will no longer be filled properly.
This is to allow people to set temporary local variables by injecting
them directly into the context via some decorator or some other
mechanism. Contexts are not kept alive long enough to warrant being
slotted.
Previously it would both forward and invoke depending if there were no
kwargs given. Now it just passes in the arguments to another command
without doing any special casing on the no argument case.
