I'm a somewhat experienced coder but I am relatively new to Haskell.
I've got a question about whether a usage of do notation is idiomatic,
or whether it's better to use pattern matching.
I've got two functions which take an input and return Maybe SomeType.
If either returns Nothing, I also want
The do notation in this instance yields a nice advantage: if you want to
switch to a different monad to encapsulate failure you will meely need to
swap out the type signature and your function will need no further work.

Also if you don't need foo and bar you can write:
callFoo callBar return baz

With do notation, I can write something like this:
do
foo - callFoo x
bar - callBar x
return (baz)
