As a space-saver measure, I'd like to have a function like pascal's println
in the systemtap language:
println (EXPR [, EXPR]...)
which would be equivalent (rewritten) to:
printf ("%.%.%.\n", EXPR, EXPR2, EXPR3)

How about also an alternative that allows an arbitrary delimiter? Seems like
people would often want to output a list of things tab- or comma-delimited.

I think it would be easy to generalize this into a set of print variants that
should cover just about anyone. I propose adding two new suffix variants to
print-like statements: 'd' for delimited, and 'ln' (or perhaps just 'n') for
including a newline. With 'd', the first parameter must be a string literal
that will delimit the rest of the arguments. With 'ln', a newline is appended.
Bare print() and sprint() would be extended to allow multiple arguments, which
just get printed one-after-the-other.
So the complete list of print statements would be:
print, sprint, printf, sprintf, printd, sprintd,
println, sprintln, printdln, sprintdln
We have a special case of print(@hist_*) -- I'll leave that as-is.
Any comments? If there are no objections, I will implement this...
Josh

I have committed changes to implement all of these.
