Weeklies

Weekly Challenge #356 is available for your enjoyment.

Raku Tips ‘n Tricks

This week, it was reported that the fast code here is 13x faster than the slow:

my @a = 1,2,3,4,5; 

sub foo($a, @b) { }; 

foo(@a.head, @a.skip)  #fast 
#foo(@a[0], @a[1..*]) #slow

for ^1_000_000;

This seemed a little surprising to me, so I thought I would reach for the profiler:

raku --profile myscript.raku

Ahhh, that’s 26 million call frames vs. 700 thousand, not surprising its a tad slower. Profiler also, err, profiles your code with a neat Call Graph view, to show where the hot spots are so that you can focus your tuning on the critical sections. Other optimisation tools are available.

Your contribution is welcome, please make a gist and share via the raku channel IRC or Discord.
