as to if when thinking of it the if construct has such parts

if X then S else E

and the keyword if is not necessary imo as the expression x return 
logical value them then can be used on this without if

X then {}
X else {}

i would prefer to denote (at least temporerely) then as ->
and else as ~> then you can build construct like


a -> b -> c -> d ~> e ~> f

when the arrows take logical value of the left
(if a true then b, if be true then c if c true then d,if
d false then e and if e false then f)

but some need also to use else to some previous espression and
i think how it could be done but maybe just parenthesis can be used

a (->b->c) ~>z

if a true then b and if b true then c but if a false then z
