Hi Chapel Users --
We wanted to highlight a question that came up recently on a sibling
thread in hopes of getting feedback from the community. Perhaps most
simply, given the following code:
var i: int(32) = 42;
foo(i); // call requires coercion from int to real
proc foo(x: real(32)) { writeln("In 32-bit version"); }
proc foo(x: real(64)) { writeln("In 64-bit version"); }
Which of the two calls would you want/expect foo() to dispatch to (if
either one)?
While this example is fairly arbitrary, note that this has implications
for things like which math operators are invoked in cases where there is
no precisely matching signature for the two argument types, such as:
...i * 2.5...
We'd appreciate hearing any heartfelt opinions on this topic. Opinions
with supporting rationale are particularly appreciated.
Thanks,
-Brad
