Not the first byte of a word.
# starts a comment only when it is the first byte of a word.
You can write:
some_var= #Now this is a comment, since there is space between = and #
if you meant for some_var to be assigned the empty string, or write:
some_var='# Embedded as part of the assignment'
if you meant to include more than just the # in the value assigned to
the var.
