Right now, the property parser function allows one to fetch the corresponding value of a claim/statement on Wikidata. However, this is not enough for cases like accessing qualifier-specific data (e.g. metropolitan and rural population of a location).
Considering this item on Wikidata, that would be good to have a new parser function to fetch different population figures, so
{{#property:P1082|from=Q2674064|q1=P585|v1=2014|q2=P518|v2=rural area}}
would yield the value 12877.
