v1.4.1

Fixed

• Local functions (e.g., local function f()end) are not converted to local
  variable assignments (e.g., local f=function()end), as they are not
  perfectly semantically equal.
• In table constructors, use record-style fields ({a=1}) in place of
  expression-style fields ({['a']=1}) only then the key is a valid identifier.
  For example, {['foo/bar']=1} was getting converted to {foo/bar=1}, causing
  crash.
• Functions with named and varargs crashed the parser (e.g.
  f=function(x,...)end).
