| size_t star_height | ( | ) | const [inline] |
Compute the star height (h) of the expression (E).
Definition: if E=0 or E=1 or E='letter' then 0 if E=E1 + E2 or E=E1.E2 then max(h(E1), h(E2)) if E=F* then 1 + h(F)

| size_t length | ( | ) | const [inline] |
Compute the length of the expression, i.e.
the number of letters used in the expression.
