Hi,
i adapted a #lang and REPL for SRFI 105: https://github.com/damien-mattei/library-FunctProg/blob/master/racket/SRFI-105.rkt a simple example can be found here: https://github.com/damien-mattei/library-FunctProg/blob/master/racket/examples-curly-infix.rkt The two files must be in the same directory. any files using curly infix notation must begin with: #lang reader "SRFI-105.rkt" example at REPL: Welcome to DrRacket, version 8.2 [cs]. Language: reader "SRFI-105.rkt", with debugging; memory limit: 128 MB. > (define a 2) > (define b -3) > (define c 5) > {{b expt 2} - {4 * a * c}} -31 Any advice about other enhancements or other way to implement a REPL or language for SRFI 105 "curly infix" with Racket are welcome.
