Slow compared to map?

[kokizzu]

Hi, i was trying to benchmark haxmap vs map,

https://github.com/kokizzu/kokizzu-benchmark/blob/master/assoc/go-haxmap/haxmap.go vs https://github.com/kokizzu/kokizzu-benchmark/blob/master/assoc/map.go the diff https://pastebin.com/diff/V3Y04Uha

but haxmap took like 51s vs 14s using map

time go run go-haxmap/haxmap.go
