diagnose a mismatch of a closure body with its inferred return type.  For
example:

t.swift:2:39: error: invalid conversion from type 'double' to 'int'
var closure5 : (double) -> int = { $0 + 1.0 }
                                   ~~~^~~~~
t.swift:2:34: note: while converting closure body to inferred return type 'int'
var closure5 : (double) -> int = { $0 + 1.0 }
                                 ^ ~~~~~~~~
t.swift:2:1: note: while converting 'var' initializer to declared type '(double) -> int'
var closure5 : (double) -> int = { $0 + 1.0 }
^
