I came across a compilation error when using Math + the "only" clause:
use Math; // compilation is successful
// use Math only pi, sin; // compilation fails
const a = 0.0;
const b = 2*pi;
const n = 200;
const dx = (b-a)/n;
const x = [i in 0..n] i*dx;
const s = sin(x);
When using "Math" alone the program compiles without issues. When using "Math only pi, sin"
the program does not compile, with the following error:
promo.chpl:8: error: unresolved call 'chpl_promo1_sin(x=[domain(1,int(64),one)] real(64), tag=iterKind, followThis=1*range(int(64),both,one))'
promo.chpl:8: note: because no functions named chpl_promo1_sin found in scope
I don't know if this is a compiler bug, or if I am missing something about employing "only" + promotion together.
