Juxtaposing strings only works with constants, which may be convenient
in some cases, but it won't work at all when concatenating other string 
values.

a="hello"
b="world"

a+b    # will yield "helloworld" but
a b    # is a syntax error

Using + is arguably preferable when you have a choice to make, since it 
works in all cases, including constants.
