There is actually a valid reason for maintaining the pattern:
if (Debug.verboseOn()) {
Debug.logVerbose(string + concatenation + here);
}
In fact string concatenation (in any of its forms) adds some overhead
(computational, memory, garbage collection); since the string concatenation
is done before calling Debug.logVerbose (or similar methods), but it is
only useful if that log level is on (otherwise the call to logVerbose will
not produce any output) then it is wise to perform the verboseOn() check
before: if the call returns a false then at runtime the sting concatenation
will not be executed at all.
