@MQRY and on-the-fly data retrieval

Mix together my last two posts, Formula language in a JavaScript world: JSON db lookups and Choices in your on-the-fly data retrieval, and you get an odd but powerful concoction I have nicknamed @MQRY (Midas Query formulas). All this took to implement was current working code in the Midas C++ API exposed in formula language calls. Consider this the art of the possible.
Since formula language calls can be made from LotusScript, Java, and Javascript using calls to evaluate, and can also be used in computed text, computed fields, etc, this makes a versatile general query tool. Selection of documents and values can be as broad as across multiple databases and as narrow as retrieving elements from inside rich text, or both at once. In this case, the two calls would return exactly the same data as in my Choices post.
Would you like to see something like this in Notes/Domino 11? How about in Domino 8.5/9/10/11?
REM {Example of handlng query and retrieval in one call, returning JSON};
json := @DbCommand("MQRY":"NoCache";
@DbName:"SELECT MaintVerNum=\"9.0.1 FP10\"";
"SPRnumber,APARID,Client_Server,OfficialDesc,Project,Regression{B},SecurityIssue{B},TRIAGEMODDATE";
"IncludeUNID='Yes' Sort='Yes' Title='SPRNumber' Format='json' JSONFormat='Mongodb' ");
REM {Example of handlng query and retrieval in one call, returning XML};
xml := @DbCommand("MQRY":"NoCache";
@DbName:"SELECT MaintVerNum=\"9.0.1 FP10\"";
"SPRnumber,APARID,Client_Server,OfficialDesc,Project,Regression{B},SecurityIssue{B},TRIAGEMODDATE";
"IncludeUNID='Yes' Sort='Yes' Title='SPRNumber' Format='xml' ");
