  The original lfe_scan.erl is a continuation-passing, character-list LFE
  scanner. pe_lfe_scan.erl adapts its scanning clauses to operate on a binary,
  to keep line+column positions on every token, and to emit comments as trivia
  tokens rather than discarding them. The surface grammar (symbols, numbers,
  strings, based numbers, characters, hash forms, and comments) is ported from
  lfe_scan; see the per-clause attributions in the module.
