[I have extended it to two lines for what I hope is better clarity.]
But Bart's condition begins with (), and I am having the darndest
time discovering what
this means.
without the () the line would be <$(ws)

the () acts as an escape on the < and is stylistically preferred to
\< when at the beginning of a pattern, although I believe the effect
is the same.
