Elegant...
I wasn't aware of the 'seq' command/builtin
 [hence my "yes|head|tr -d '\n' "]

The Rosetta people made a distinction between "Unix Shell" and "Unix
pipeline", which I find a little arbitrary and confusing...

Didn't look further to find how they drew the line.

I like your one-liner better :-)
