​Folks,  one more thing to consider: the next big release of yaql (1.0,
coming really soon) will get support of curly brac​es (by default - to
initialise dictionaries in the following way:

v0.2/v0.3 syntax: dict(key1=>value1, key2=>value2)

v1 syntax: {key1=>value1, key2=>value2} (the old syntax works in v1 as well)


So, {} will become a valid yaql expression (empty dict). I believe it is
not a big deal to parse that correctly and differentiate between outer
markup and an expression contained within, however statements like <{{}}>
may be a little ugly.
