jekyll: a hyper-declarative, statically-typed programming language around environment manipulation

# x is introduced to the environment
{ ..?e } → { x := 3 ; ..?e }
# y too ; ?e is not the same row variable as the one above
{ ..?e } → { y := 5 ; ..?e }
# matching the current context on one that contains an x and a y
# which allows us to add them to introduce y
{ x ; y ; ..?e } → { z := x + y ; ..?e }
