1. STDFLTR_ALPHA only?

We've got STDFLTR_ALPHA. It's defined as

public constant STDFLTR_ALPHA = routine_id("filter_alpha") 

where filter_alpha is defined as

function filter_alpha(object elem, object ud) 
	return t_alpha(elem) 
end function 

and t_alpha as

public type t_alpha(object test_data) 
	return char_test(test_data, Defined_Sets[CS_Alphabetic]) 
end type 

There are other cool t_* out there like t_digit and t_cntrl but they don't have STDFLTR_*. Deliberate? Accidental? An exercise for the programmer?
