Consistent all caps for constants?

[sra1, 2012/04/05 21:23:08]

Done.

Drop argument if unused / unnecessary.

Done.

Do you mean to use the uppercase VERSION in this line and the lowercase version
in the line above?

[sra1, 2012/04/05 21:23:08]

Done.

[vsm, 2012/04/05 20:11:28]

Perhaps just call step1 directly instead of the andThen continuation.  Note, you
do call step2 directly from step1.

[sra1, 2012/04/05 21:23:08]

Done.
