Should we have prettier string printing for exceptions and std elemts?

FWIW I tried to propose a `dump` function one year ago [1].
There has never been a great interest in it though as while using 
`writeln` is a bit annoying (e.g. no spaces, no variable names) 
apparently all core people got used to it already ;-)

If someone considers to add a pretty printing method he/she, this 
new symbol could also be very useful for single elements too (and 
thus gain chances in its acceptance).
