in thread pop an array

Strictly speaking the scalar is unnecessary. An array in a boolean context is true if it has elements and false if it's an empty list. 

$ perl -le '@a = (); @b = (1); print "\@a" if @a; print "\@b" if @b;'
@b

    Strictly speaking it isn't necessary. I usually add it for clarity. TMTOWTDI.

    (This is off-topic, but I never use scalar with @rrays. I use 0+@array. Indeed, most often uses of scalar can be changed to the shorter 0 + something or "" . something)
