tib timotimo : there is difference but it's very small 17:20
even by declaring inside the loop (which is maybe not sufficient to stop optims)
Str -> Int seems to be very slow in comparison : for (1..10_000_000) { my $n ="123"; $n++; } 17:26
timotimo : actually there is well coercion in each iteration 18:07
means for(1..1000) { $^item.starts-with($n) } will do 2000 calls to Str method (multi method Str(Int:D: --> Str:D) {) from src/core.c/Int.pm6 18:09
BUT
for(1..1000) { $^item.starts-with($s) } will do 1000 calls to Str method (multi method Str(Int:D: --> Str:D) {) from src/core.c/Int.pm6 but also 1000 calls to Str method (multi method Str(Str:D:) { self }) from src/core.c/Str.pm6 18:10
so at the end both has 2000 calls but not the same methods and I think it explains the small difference I reported (like 4 or 5 seconds on 30secs when you run 100_000_000 iterations) 18:12
tib (Just for precision, the other 1000 calls that never change are the coercion of $^item) 18:38
