RE: [sv-bc] confusion in determining the type of an self determined binary expression during evalution of type operator

Yes, and somebody has to clean this mess. The definitions as they appear
right now have little sense and, not surprisingly, are not used
consistently through the LRM. For example, the 7.4.6 section with its
definitions of part-select, slice, slice name and indexed name, creates
such a big confusion that any further references to these terms leave
the reader in complete prostration. Not surprisingly, the terms like
"slice name" are not even used anywhere aside their definition. The
presence of additional related definitions in other sections makes the
situation even worse. The LRM should have been defined a single term,
like "select", or "part select", or even "slice" to refer universally to
any kind of  "select" and then should have used this term everywhere.
Perhaps it would be OK to have a couple of specialized terms likes
"field select" to ease explanation in certain cases, but in majority of
references a single general term should have been used, to avoid
confusion.

7.4.6 defines 'part-select' and 'slice'.

 

11.5.1 defines 'bit-select' and 'part-select'.

 

11.5.3 defines 'field select' and 'indexing select'.

 

11.5.3 uses 'array select', but that is not used elsewhere.

 

Table 10-1 use 'Array element select' but 'element select' is not used
elsewhere.

 

'member select' is not used anywhere.

 

9.2.2.1 uses 'select expression'.

 

11.5.3 uses 'select'.

	[Yulik] The problem here is that the LRM is very confusing on
the definition of the related terminology. I have tried to raise this
issue in the past, but it didn't get much attention. The end result is
that I and all my colleagues just use the "part select" term as a
universal term describing any kind of "select"/"slice"/"part
select"/"bit select"/"member select", even that we know that strictly
speaking LRM assigns some other mysterious meaning to this term. It
looks that you're using the term "select" for such a universal meaning;
but I don't think LRM clearly defines it as such either.
