Advanced Editor for DAX Columns and Measures

I would like to see an editor where I can define all of my DAX columns and measures similar to Advanced Editor for Power Query/Query Editor. Though I would like to see it with a C# scripting syntax by defining the object type, and delimiting EOL using a semicolon.

Idea:
column _dcMyColumn1 = IF(this = BLANK () , that, this);
column _dcMyColumn2 =
VAR sOther = "Something"

RETURN
IF(
this = sOther,
that,
this
);
measure _dmMyMeasure = DISTINCTCOUNT(Table[Id]);
measure _dmMyMeasur2 = SUM(Table[Cost]);
