New issue on get__() versus get() #1483
Description
This came up in the reverse depends check for #1482, but reproduces locally for me. Package RestRserve has a .hasAttribute() check, and that fails on

It does indeed go away if we replace get__() with get() here:
Rcpp/inst/include/Rcpp/proxy/AttributeProxy.h
Line 100 in 8d2f8f8
