Invalid exception class and error message when executed in irb

[frsyuki]

When a script is executed in irb, and type conversion error happens, TypeStruct raises ArgumentError with an unexpected message.
But TypeStruct::MultiTypeError is expected.

How to reproduce:

$ irb -rtype_struct
irb(main):001:0> c = TypeStruct.new(v: TypeStruct::ArrayOf.new(String))
=> #<Class:0x007fab65881360>
irb(main):002:0> c.new(v: 1)
ArgumentError: different prefix: "" and "/Users/frsyuki"
