Re^2: To be, or not to be, an object ?

There are, 2 aspects to the differences between my attempt and Grahams' (author of Scalar::Util), Graham...
creates a temporary method in the UNIVERSAL class

Scalar::Util uses UNIVERSAL::a_sub_not_likely_to_be_here, but it's not a temporary method, because (unless I'm mistaken) it stays in the UNIVERSAL namespace forever.

However, the XS version of Scalar::Util is pretty straightforward, it's blessed() does not use any dirty tricks at all, it just determines whether something is blessed, using the appropriate API.

TFT, point taken. I would point out that temporary and forever are one and the same in this context i.e. the lifetime of the program `use`ing Scalar::Utils. At last, a user level that overstates my experience :-))	[reply] [d/l]
