I am curious ...
The functions max and min are defined over a tuple to return a tuple of
the same type as per page 123 of the specification. You can also do
var x = max(int(32))
and that works. Nice. I am curious at the semantics of that.
You also have max and min appearing in reductions nicely documented in the
specification.
However, also
x = min ( 10, 50)
returns x == 10.
But this seems to only appear in
https://chapel-lang.org/docs/latest/builtins/internal/UtilMisc_forDocs.html
which I found only by accident. It might be nice to stick that somewhere
in the next revision of the specification or at least cross reference it.
In a 'reduce', max and min seem to be interpreted as operators and in
other cases as overloaded functions. Is this true or do I just totally
misunderstand the difference between a function/proc and an operator?
If they were operators as they appear to be in reduce you could say
x = a min b
to yield the minimum of 'a' and 'b'.
G++ uses the extension '>?' and '<?' for max and min operators. I am mixed
about whether I like them.
