Multiple elems for the same templates

[vithar]

I have this code in my project:

block('regions')(
    elem('region')(
        tag()('span'),
        match(function() { return this.ctx.url; })(
            tag()('a'),
            attrs()(function() { return { href: this.ctx.url }; })
        )
    ),
    elem('currency')(
        tag()('span'),
        match(function() { return this.ctx.url; })(
            tag()('a'),
            attrs()(function() { return { href: this.ctx.url }; })
        )
    )
);

As you can see, templates for region and currency element the same. Can we implement support for multiple arguments in elem (e.g. elem('region', 'currency')) or ability to pass array as argument (e.g. elem(['region', 'currency']))?

@tadatuta why not make multi-selectors like in CSS with , delimiters?

For elems:

block('regions')(
    elems('region', 'currency')(
    )
)

For blocks:

blocks('regions', 'smegions')(
)

@vithar take a look at https://github.com/bem/bem-xjst/pull/165

Isn't enough elemMatch()?

[vithar]

It is enough, thanks.

[blond]

So, what about multi-selectors?

[tadatuta]

@blond that's too rear case to provide such sugar

[blond]

@tadatuta, sugar affects performance?

[tadatuta]

it extends API without necessity
