Wanted: simpler metas syntax #51

The current metas syntax is, IMO, overly noisy and verbose. I'd like to see it simplified from

◊meta('key "value")
◊meta('key2 "value2")
◊meta('key3 "value3")

to something more like:

◊metas(
    key "value"
    key2 "value2"
    key3 "value3"
)

The current metas syntax is, IMO, overly noisy and verbose. I'd like to see it simplified from ``` ◊meta('key "value") ◊meta('key2 "value2") ◊meta('key3 "value3") ``` to something more like: ``` ◊metas( key "value" key2 "value2" key3 "value3" ) ```

The Pollen parser gathers tags of the form ◊meta('key "value"), but you can invent your own syntax for generating those tags, e.g. —

#lang pollen/markup

◊(define (metas . kvs)
   (define meta-tags (for/list ([(k v) (in-hash (apply hash kvs))])
                       `(meta ((,k ,v)))))
   `(span ,@meta-tags))

◊metas['key "value" 'key2 "value2" 'key3 "value3"]

The Pollen parser gathers tags of the form `◊meta('key "value")`, but you can invent your own syntax for generating those tags, e.g. — ``` racket #lang pollen/markup ◊(define (metas . kvs) (define meta-tags (for/list ([(k v) (in-hash (apply hash kvs))]) `(meta ((,k ,v))))) `(span ,@meta-tags)) ◊metas['key "value" 'key2 "value2" 'key3 "value3"] ```

Yeah, I know the parser currently picks up ◊meta('k "v"). And I know I can come up with my own; this is me requesting for a more convenient metas syntax to be added to pollen proper, because I think there is enough value in this that it shouldn't be reinvented by everyone who wants it.

(Once I get up to speed on Racket (ahhh, sweet memories of Scheme in intro CS classes), I'd be happy to contribute a patch to that effect, but for now all I have is a github issue.)

I’ve just pushed a fix to allow multiple key/value pairs within a meta tag, so this:

◊meta['key: "value"]
◊meta['key2: "value2"]
◊meta['key3: "value3"]

Is equivalent to this:

◊meta['key: "value" 'key2: "value2" 'key3: "value3"]

This change is OK with me because it extends the existing syntax in a simple & intuitive way.
