This macro was recently updated to skip testing for non-existent or

patch provides another variant, which still uses the fast-skip mechanism
but without requiring the temporary, for the cost of a slight increase
in code size (~20 bytes per callsite).
Slight? Next.

106 bytes out of 1166488; that's 0.009% or 91ppm.
The adjective "slight" definitely applies :)
