I'll defer to your (clearly better) understanding of Rake :)

Certainly; but that's a problem for Rails (or rather, Rails
developers) to solve, if indeed it really is a problem.
I'd say this shares more in common with reopening classes - certainly
any number of files might reopen a class and redefine a method,
obliterating what was there before, but it still qualifies as a
If the "task => method" analogy holds, might it be possible to define
an alias to the current implementation of a task, and then redefine it
to call the aliased task along with any custom behaviour? Maybe
something like this:
alias_task :new_task_name, :original_task
redefine_task :original_task do
... perhaps something like that? It may be that this is simply not
practical, in which case I think that it's still fine to simply lose
the previous implementation - that feels Rubyish to me.
