I don't call that "alignment", I call that "evil".
As far as I am concerned, one of the core rules of
good indentation is
- the presence or absence of line breaks will
depend on the size of names and constants
- but the AMOUNT of indentation never will.
Why? Because indentation is supposed to reveal
STRUCTURE, not spelling.
I would write this as
my_function(
A, B, C, D, E
) ->
I know Lisp has traditionally used this style,
but I decided decades ago that it was wrong,
and I've never regretted it.

This I _do_ align, sometimes. It's not a case where I would
ever have found tabs useful anyway.
I also try to align blocks of related end-of-line comments
so they start in the same column. For that I used to use
tabs, but found it a pain.
