When logging something requires expensive operations, it would be nice to be able to skip the work if it won't be logged.

For example, instead of:
```
let serializedComplexObject = expensiveOp();
logConsole.trace(serializedComplexObject);
```
one could do:
```
if (logConsole.logLevelAtLeast("Trace")) {
  let serializedComplexObject = expensiveOp();
  logConsole.trace(serializedComplexObject);
}
```
