- "count" can now be a string defining a comparison in the form of
'<operator> <value>', for example: '> 12' or '!= 1'. If its value
is not a string, it is assumed to be a concrete integer as before.
- "keyword" can now be a dictionary defining tests for individual keys.
These tests can either be a type, a concrete value or a regex
starting with "re:". Dictionaries can be stacked inside each other.
Optional keys can be indicated with a "?" before its name.
For example:
"keyword:" {
"image_id": int,
"gallery_id", 123,
"name": "re:pattern",
"user": {
"id": 321,
},
"?optional": None,
}
