I suppose this is because the ampersand identifies the token as a function name, and so Perl doesn't have to spend any time disambiguating it

No, I don't think it to be the reason. AFAIK the difference lies in the fact that object methods can be overloaded, or inherited, and this is managed at run time, while direct function call is managed thru the symbol table built directly at compile time.

The difference between the overloadable method calling convention and the non-overloadable function calling convention is what I originally set out to measure. The ampersand variation, which was what surprised me, is limited to the function calling convention in the sample code. -- Marvin Humphrey Rectangular Research ― http://www.rectangular.com	[reply]
