signature(object = "Distribution"):
from distr-2.6 onwards, we provide this as a synonym for
method q; this synonym more explicitely states that we are dealing with
the left-continuous variant of a quantile function. It is useful in particular
when used from the console in RStudio, as RStudio catches calls to
q() and treats them separately from usual R evaluation.
The developers of RStudio have been asked to fix this and comply with standard
R evaluation which explicitely allows overloading q() as we do it in this
package, but so far have refused to do so, as they claim overloading
q() was insane.
