+1 Yes, specifying the language to use when interpreting some source, is best in the input source itself than in the reference to that source.
But why must it be one or the other, and not some sensible combination of both. e.g. If the #lang is absent from the source, look for and/or override the language to use with command line switches to the interpreter, with #lang racket (or racket/base or something else) as the default. The only way Racket-created solutions can supplant the products created with medieval tools (and I'm thinking here of lex, yacc, and their ilk) is by ingesting the exact same input source files/streams that those other products ingest. Forcing a change to input source is an unnecessary, difficult, and often insurmountable hurdle. Evolving replacement Racket-built solutions in (one of the many) domains where Racket is ideal should be easy. > On May 7, 2016, at 6:48 AM, Jay McCarthy <jay.mccar...@gmail.com> wrote: > > +1 > >> On Fri, May 6, 2016 at 6:13 PM, Jack Firth <jackhfi...@gmail.com> wrote: >> William's remark is spot on about my use-case.
