the period/full-stop is not a required terminator, as in the C
language - it is separator, between message chains - that is: it
is not required after the final LOC

a period/full-stop can follow a right-square-bracket ']' in most
syntax - all of these forms are valid syntax

i suppose that you are seeing an error with a period/full-stop
after a method definition - that syntax is something of a
special form for gnu-smalltalk - most smalltalk dialects do not
use square-brackets to enclose class and method definitions
