Often I have a function that I want to apply to a pipeline conditionally.
I'm forced not to either write a "maybe_do_x" function or use an inline
check with then/2.
Now that we have then/2, I'm thinking it might be nice to have then/3 so
that we don't need "maybe_" functions anymore, improving
No opinion on whether this function exists or not. But, if it did, I think
the second argument should be a function, so that conditionality can depend
on a property of the first argument.

I think this has been brought up a few times and not sure there's a great
need for it. It can't (shouldn't) happen _that_ many times, because if
you're not going to do something with the result of a function the chances
are you should be bothering to do_something() to the function anyway. And

Hi!
Thanks for the elaborate response!
> You have to write "write_y()" function anyway, so create a version that
has a no-op version that simply returns the argument:
Sometime write_y is already there and then you need to write a wrapper
function. Also I really try to avoid putting a boolean i
I don't believe we should necessarily be leading people to encode more
logic into pipelines. For example, sometimes the value that is in the
conditional comes from the pipeline, other times it is simpler to pattern
match with "case" or "with", etc. Or just a plain old conditional. It
should also be
