You are mixing two different things. The constructions
|foo=function(x)...end| and |function foo(x)...end| have exactly
the same meaning.  The "subtle" difference is between 
|local foo=function(x)| and |local function foo(x)|. Note that the
second form is an explicit construct in Lua,
not a |function foo(x)| inside a common 'local' declaration.
