DAX Comments in Power Pivot Measures

Is there a way to use comments in DAX measure formulas in Power Pivot? I tried both //...., and /*...*/, and while they show up in blue initially and seem to be understood as a comment, they disappear when the model calculates.

I figured out the solution to this. Sharing in case anyone else runs into the same problem. It seems that Power Pivot will remove comments in DAX code if they are not on a single line, and the single line has to be surrounded by other lines (can't be the last line). Seems like a strange bug. Why can't I end my code with a comment?

Measure:=SUM([Amount]) //This comment will be deleted by power pivot

Measure:=SUM([Amount])

//This comment will also be delted by power pivot

Measure:=SUM([Amount])

//This comment will be maintained because the next line is not blank

Measure := //Apparently this comment will also disappear

SUM ([AMOUNT])
