RE: [sv-cc] 'Scalar' term for SV function results, etc.

I like the term "atomic" for these value/types.  FYI, the BNF uses it
for the integer data types (see
"integer_atom_types"), but stops short of doing the same for "real",
unfortunately.
 
Other thoughts ?

	Shalom,
	 
	1. The intent certainly is to distinguish a single value from
aggregate/composite values.
	2. Despite the original, non-vector meaning, common use of
'scalar' does seem to mean single value:
	        http://en.wikipedia.org/wiki/Scalar_%28computing%29
	3. The SV definition of 'scalar' as 1-bit wide is in 6.8.
	4. String appears to be included because we are indicating the
pointer to the string, rather than the string, itself.
	5. 'Singular' seems reasonable; the only obvious alternative is
to spell out that it's not 
	    an aggregate or composite (e.g., array, vector, structure).
	 
	Does anyone some memorable and snappy alternative?
	 
	Ralph

		In SV, a scalar is a one-bit value. "Singular" would be
closer.

		A possible replacement for this term is "scalar values".
		
		That is the term used in VHDL and is probably less
vague.

		Hi,
		
		In Draft 3, 34.2.2 says,
		
		A rich subset of SystemVerilog data types is allowed
		
		for formal arguments of import and export functions,
although with some
		restrictions and with some notational
		
		extensions. Function result types are restricted to
small values,
		however (see 34.5.5).
		
		and 34.5.5 has a similar statement and details the exact
restrictions.
		
		However the phrase "small values" sounds strange.
		
		In what way are real, longint, and string 'small', for
example?
		
		Thanks,
		
		Shalom
