MakeExpression


Dear Reader,

Consider the following Mathematica problem. How does one incorporate
pattern matching conditions with the command MakeExpression?

The following does NOT work:

MakeExpression[RowBox[{a_Plus, "[", b__, "]"}], StandardForm] := 
  MakeExpression[a, StandardForm]

Any form of condition used at the lhs seems to be ignored.
