What are the backticks `` called?

Question

What are the backtick operators (``) called in the context of evaluating their content?

Answer 1

In Perl, the backtick operator has a synonym: qx//. The q and x stand for "quote & execute." You'll see it referred to as 'command' too, but frankly, in the Perl community and throughout most of the Perl documentation, they're just called the backtick operator or backticks. Calling them anything other than backticks or the backtick operator in the context of a Perl program will simply make it harder to know what one is talking about.
