To refer the current parselet itself, as self keyword might be useful. This is also relevant for #10

@{ Self 'T' | 'T' }  # matches T TT TTT TTTTTTTTT...

9070985 introduces a case where the Self parselet is obligatory: Due implementation of the Token prelude parselet in #51, the Token parselet from tokay.tok uses this Token, and needed to be renamed to Token1 to behave like before. The use of Self in this case would redefine Token without use of its previous definition.

Another note on this:

  • self references the current parselet in runtime-mode
  • Self references the current parselet in compile-time mode - may only be used when the parselet is consuming!
