These tests exercise the various isXxx, isXxxType, isXxxValue predicates.
They differ in how the predicates are invoked.

* isX.module-writeln.chpl

applies the predicates to module-level variables
and displays the result using writeln().

* isX.byBlankArgs-compWarns.chpl

applies the predicates to a blank-intent formal argument
and displays using compilerWarning.


Other variations on this test could be added, e.g.:
- apply the predicates to local variables,
  formals, directly to types, etc.
- display the results using param if and compilerWarning, e.g.
    result = isXxx(yyy);
    if result then compilerWarning("yes");
              else compilerWarning("no");

These tests were generated automatically by running:

  src/isX.gen

and added to version control for ease of use.

* isX.sync-by-const.chpl

This test checks isInt() for int vs. sync int formals.
It was created by hand.
