Warning if variable name contains builtin api name

I have a 7.X function "basicLocalCurlGetWithTiming.json" that used to import and work fine.  I now get an error that says:

Function tries to overload following builtin API(s): curl

If I edit the javascript and global replace the word 

• curl with rest

then replace

• rest( with curl( for the actual function call

the issue goes away, not sure if it is the variable names, comments, or strings in he log calls.

Update: You can replace the variable do_curl with do_rest and the issue will also go away.
