Rays
Either a variable (uppercase, possibly followed by digits) or a polarised (+/-)
or unpolarised (lowercase, possibly containing _ and digits)
function symbol applied to other rays (or nothing in case of constants):
X, a, f(X), +f(X), -f(-h(a, Y1), X2), +add_dec(0, 2, 2).
Commas can be omitted:
-f(-h(a Y1) X2), +add_dec(0 2 2), string(hello i am X).
Cons
There is a special binary infix function symbol : which can be used to
concatenate rays:
a:X, a:b:b:X, f(a:X):+f(0:1:X):-f(Y).
Stars
An unordered sequence of rays ending with a semicolon ;:
X a +f(X);
Constellations
An unordered sequence of stars:
X a +f(X); -f(-h(a Y1) X2);
+add_dec(0 2 2);
All variables are local to their stars, hence the occurrences of X in the
first line are distinct from the one in the second line.
Focus
You can prefix stars with a @ symbol to put a focus over them. This will
affect the behaviour of computation:
@X a +f(X);
@-f(-h(a Y1) X2);
+add_dec(0 2 2);
