I don't ask anything for addsiren.

but how store the weapon name if the parameter is unchangeable?
native GetWeaponName(weaponid, const weapon[], len);

another example:
0.3.7:
native SetPlayerName(playerid, const name[]); //ok good for SetPlayerName(1,"Miguel"); //"Miguel" is constant
native GetPlayerName(playerid, const name[], len); //what? xd
