Comment(by ryani):
I would suggest never doing dependency analysis with rec (I was actually
unaware that this happened and thought that was the whole point of
migrating to 'rec' over 'mdo').
I second the suggestion that we translate
{{{ do { ... ; rec { ...; e } } }}}
(i.e. 'rec' as the last statement in a do block) into
{{{ do { ... ; rec { ...; fresh <- e} ; return fresh } }}}
And translate
{{{ do rec { ... } }}}
into
{{{ do { rec { ... } } }}}
