``++echo++`` can be called with or without parentheses, but it is best practice to leave parentheses off the call because using parentheses with multiple arguments will result in a parse error.
== Noncompliant Code Example
----
echo("Hello"); // Noncompliant, but it works
echo("Hello", "World"); // Noncompliant. Parse error
== Compliant Solution
echo "Hello";
echo "Hello","World!";
