barDump() etc., prints arrays and objects in a clever way. They
generate HTML code only for those parts that are immediately visible, without

This, on the one hand, will significantly reduce the amount of HTML code, but
above all it will speed up its display, because the browser does not have to

By default, the contents of these keys are not printed:
You can use PSR-3 loggers in Tracy, and vice versa. This is done by a pair
One more thing
And finally, one thing that connects Tracy and Latte. Tracy can utilize
source mapping provided by Latte and display not only the line where the error
occurred in the generated PHP code, but also in the template.
