Some times I may want to do something different in the code for a particular language.

Ie:

Currency::create('val_frete')
                ->label(Lang::t('Freight'))
                ->BRL()
                ->symbol()
                ->decimals(2),

Here I'm hard setting the currency format to BRL but, if EN is selected, I would need to change it to USD.

Is there a getLang() or something?

Thank you.

Since I'm doing just 2 langs, I did it like:

Currency::create('val')
                ->label(Lang::t('Endorsed'))
                ->symbol()
                ->decimals(2)
                ->{(strpos(Lang::name(), 'PTBR') !== false)? 'BRL' : 'USD'}()

But I really would like an easy way to set currency based on the used language.

First I guess would be cool if currency autodetected the used language. But if it's too troublesome, some quickier way to set it would work well too, for example:

Currency::create('val')
                ->use(Lang::name())

Yes, you are right about that. Thank you.
