Print current stacktrace

Is there a function ready to use that prints to stdout/stderr the current stacktrace from the point it is invoked ?

Does println(stacktrace()) do what you want?

I sometimes use:

foreach(((ii,frame),)->println("[$ii] $frame"), enumerate(stacktrace()))

Which gives:

julia> foreach(((ii,frame),)->println("[$ii] $frame"), enumerate(stacktrace()))

the numbers are nice for readabilty.
