perldoc -f print

Because print takes a LIST,
anything in the LIST is evaluated in list context,
and any subroutine that you call will have one or
more of its expressions evaluated in list context.
Also be careful not to follow the print keyword
with a left parenthesis unless you want the corre
sponding right parenthesis to terminate the argu
ments to the print--interpose a `+' or put paren
theses around all the arguments.
