Sure, but that's still kinda defeating the purpose of providing functionality that's easy to remember and type. Might as well do
time echo "#include <stdio.h>
main(n){char*b,*s=n=0;getdelim(&s,&n,-1,stdin);for(b=s;*s;++s)*s=='y'&&*s='n';puts(b);}">s.c|yes|head -n1000000|tcc -w -run s.c>/dev/null

I was mostly just pointing out that perl6 might not be as slow as the comment you linked suggests. There seems to be something about using `perl6 -pe` that caused it to be slower than you’d expected. However, using a different approach its reasonably fast, or at least it appears reasonably comparable to the perl 5 example that was provided.
Hopefully more edge cases will be discovered and fixed as the implementation matures as well.
