Re^3: difference between @array."\n" and @array "\n"

"stringifies @array"? No!

It stringifies the result of @array.

To be fair, "stringifies @array" could mean "stringifies the result of @array", but most people think of "@array" as a variable rather than code. Clarity is definitely lacking.

The concat operator evaluates its operands in scalar context, to which @a responds by returning the number 3. The concat operator then stringifies that value.

Stringification is defined as The process of producing a "string" representation of an abstract object. and "3" is for sure no representation of @array. The important point to learn is that most operators enforce scalar context of the operands, IMHO the stringification of +3 to "3" is in this case of small importance ... Just want to clarify the terminology, before people start to think that stringification enforces scalar context! Cheers Rolf	[reply]
