I will go with the name :-) The reason that we introduced this macro is that there are too many places using such conversion-and-check with almost the same error message, because most of the subsequent methods/analysis/primitives are mostly based on sref, not stmt. Introducing such macro could help alleviate the burden of writing several lines of almost identical checks and provide a consistent template of the error message. -- This is an automated message from the Apache Git Service.
