yeah it doesn't take much eye squinting to see lisp in julia. given these similarities i wonder if julia users could start to appreciate the s-expression syntax. i come from matlab then python background and i have come to really enjoy the s-expression syntax. modern IDE tools have made s-expression code as readable as pythonic pseudo-code-like syntax while affording the programmer unrivaled editing power

As it happens, in addition to the femptolisp in the Julia parser, there is actually a secret s-expression syntax for Julia itself. There's no built in REPL mode for it, but you can hack one in about a dozen lines: https://gist.github.com/brenhinkeller/44051118c2f9d18b26dc76...

nice! one annoying nit pick for me though is using commas as data separators. when you need to input data by hand into a multi dim array this can get annoying very quickly

There's https://github.com/swadey/LispSyntax.jl for that.

It's true; I think this syntax was probably made more for reading than writing since the main place it appears in the base language is just `Meta.show_sexpr`, but it's still interesting to play around with, and parsing it has some fun properties like that you can use Julia's standard syntax as effectively a preprocessor syntax for the s-expression syntax.
