To summarize the thread w.r.t. action items:
* isRange vs. isRangeType etc.: I feel we have enough votes for isRange, so
I'll go with that.
I can also provide the more specific isRangeType() and isRangeValue(), in
addition to isRange(), and analogously for the other queries. Do people feel
this would be potentially useful, or on the contrary excessive?
* _isPrimitiveType: I will retire and replace with use-specific queries.
* chpl_taskID_t - I will resolve off-list.
Answering Brad's questions:
* Q: What is a "value"?
A typical language definition deals with these key categories: types, values,
and variables. A variable is storage; a value is what is stored in a variable
(semantically speaking), and a type is a property of a value or a variable or
an expression.
Therefore, isValue(x) is the same as !isType(x). Is it valuable, then? These
two are pretty much equivalent in my view, it would be odd to have one and not
the other.
* isConst() is a legitimate query on an l-value - think 'ref' vs. 'const ref'.
If I can implement this easily, I will.
* My plans for the following are:
_isSimpleScalarType() -- leave alone. other suggestions?
_isSignedType() --> isInt()
_isUnsignedType() --> isUint()
_isSimpleIoType() -- leave alone, I don't know what it means
_isIoPrimitiveType() -- ditto
* Q: What should the behavior be for user type aliases whose underlying
definitions satisfy one of these predicates?
For a type alias that is intended to be interchangeable with the aliasee, each
predicate should return the same on both. For a type alias that is intended to
be something entirely different, the predicates we discuss should all return
false (except for the general isType); we should introduce a new predicate
isAliasType() to return true. Right now I think Chapel supports only the former.
I do not plan to do anything special w.r.t. type aliases at the moment.
