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

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?

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
