I don't know, it just seems to me that writing a try-catch block for 
each and every place where we want something more informative than a 
generic wrong-type error message is even worse than checking error_state 
in all those places.  And it is certainly much more cluttered than 
writing a single line type extraction that includes the error message 
right there on the same line.
