nl_tokens: Wrap a function in a fiber . Correctly handles expected presence of done callback
pl_tokens: function fiberize ( fn ) { return function ( done ) { var self = this ; Fiber ( function ( ) { try { if ( fn . length == 1 ) { fn . call ( self , done ) ; } else { fn . call ( self ) ; done ( ) ; } } catch ( e ) { process . nextTick ( function ( ) { throw ( e ) ; } ) ; } } ) . <mask> ( ) ; } ; }
