alright, with version v0.25a.
Here's a sample of a plugin that modifies the mantreads damage written in "SourceGolang" and the code it generated:

package main

import (
	"sdkhooks"
)

func main() {
	for i := 1; i<=MaxClients; i++ {
		if IsClientInGame(i) {
			OnClientPutInServer(i)
		}
	}
}


func OnClientPutInServer(client Entity) {
	SDKHook(client, SDKHook_OnTakeDamage, OnTakeDamage)
}

func OnTakeDamage(victim Entity, attacker, inflictor, damagetype, weapon *Entity, damage *float, damageForce, damagePos *Vec3) Action {
	if IsValidEntity(*weapon) && GetEntProp(*weapon, Prop_Send, "m_iItemDefinitionIndex")==444 {
		*damage *= 5.0
		return Plugin_Changed
	}
	return Plugin_Continue
}
