My understanding is that the blurred distinction between statement and
expression that you find in C adds a level of complexity to the parser
that (the Lua team have decided) is not justified. As a language that
is usually parsed at run-time, Lua's syntax is designed, from the
bottom up, to be parsed/compiled quickly. A strict separation between
statement and expression is a part of this.
