Valid clauses include:
  For clauses:
    for VAR from/upfrom/downfrom EXPR1 to/upto/downto/above/below EXPR2
    by EXPR3
    for VAR = EXPR1 then EXPR2
    for VAR in/on/in-ref LIST by FUNC
    for VAR across/across-ref ARRAY
    for VAR being:
      the elements of/of-ref SEQUENCE [using (index VAR2)]
      the symbols [of OBARRAY]
      the hash-keys/hash-values of HASH-TABLE [using
      (hash-values/hash-keys V2)]
      the key-codes/key-bindings/key-seqs of KEYMAP [using (key-bindings VAR2)]
      the overlays/intervals [of BUFFER] [from POS1] [to POS2]
      the frames/buffers
      the windows [of FRAME]
  Iteration clauses:
    repeat INTEGER
    while/until/always/never/thereis CONDITION
  Accumulation clauses:
