I agree with Andrei, there is no outlet for errors in the to!T function,  
exception is the logical choice.

But I also agree with you that if you don't care, it should be possible to  
ignore the errors without the cumbersome try-catch mechanism.  Something  
like:

to!(float, throw.No)(a)

or

toNoThrow!float(a)
