Style for nested if expressions?

[HarrisonGrodin]

Following up on the discussion here.

Current approach is:

if b then
  if b' then
    e11
  else
    e10
else if b' then
  e01
else
  e00

Alternative might be:

if b then
  if b' then
    e11
  else
    e10
else
  if b' then
    e01
  else
    e00

The former is better for chained if conditions in the else clauses (else if ...), whereas the latter is more symmetric/compositional.
