luxon setLocale slow execution!!!
var l,m,i,d;
for(m=(new Date).valueOf(),i=0;i<1000;i++) d=luxon.DateTime.local().plus({days:i}).toFormat('ddcccccMM');
m = (new Date).valueOf()-m;
for(l=(new Date).valueOf(),i=0;i<1000;i++) d=luxon.DateTime.local().plus({days:i}).setLocale('it').toFormat('ddcccccMM');
l = (new Date).valueOf()-l;
console.log(m,l,'-->',Math.round(1000*(l-m)/m)/10,'%++');
// expect time like:
// no setLocale: 10
// setLocale('it'):246
