It creates list context for the x operator, which causes a list to be created.

    Nope. The operand of any operator can't set which context the operator itself is in. It does set context for it's operand though. That's what's interesting. Illustration for those that don't know what Roy and I are talking about:

    sub context { print defined wantarray ? wantarray ? 'list' : 'scalar' +: 'void' } @foo = context() x 1; # "scalar" @foo = (context()) x 1; # "list"

    See perltoc if you don't know which perldoc to read!
