Convert all fns to block arg syntax. 2014-04-02 19:41:53 -07:00			`var fib = new Fn {\|n\|`
Make null falsey. 2014-01-20 18:12:55 -08:00			`if (n < 2) return n`
Fix up benchmarks and add method call one. 2013-12-07 18:43:39 -08:00			`return fib.call(n - 1) + fib.call(n - 2)`
Add trivial fib benchmark. 2013-11-14 20:57:56 -08:00			`}`

Move clock into IO. 2014-02-04 08:49:16 -08:00			`var start = IO.clock`
Range operators! Added ".." and "..." infix operators. Num implements them to return Range objects. Those in turn implement the iterator protocol, so now numeric for loops are easy: for (i in 1..10) { ... } I also cleaned up the Wren benchmarks to use this. In the process, I discovered the method_call benchmark really just showed loop peformance, so I unrolled the loops in all of the languages to stress method calls. 2013-12-25 15:01:45 -08:00			`for (i in 1..5) {`
Clean up text handling a bit: - Rename IO.write -> IO.print. - Make IO.write not print a newline. - Support \u Unicode escapes in strings. 2014-01-05 12:27:12 -08:00			`IO.print(fib.call(28))`
Get a basic benchmark runner going. 2013-11-22 08:55:22 -08:00			`}`
