Maybe stronger than you think.  I know that one of the arguments for
making ";" a C-style delimiter rather than a Pascal-style separator is
that adding a new statement at the end of a series is error-prone -- one
tends to forget to add the ";" in front of the new statement (and one
reason Pascal syntax included the "null" statement was so that "s1;"
would parse as "s1; null", making ";" a de facto delimiter).

Editing ease matters more than a little.
