Hi everyone,
can you explain me why this code DOES compile:
/*-------------------------------------------------------*/
import std.range, std.random;
void main()
{
int[] vowels = ['A', 'E', 'I', 'O', 'U'];
static assert(isInputRange!(typeof(vowels)));
auto x = randomSample(vowels, 1);
}
/*-------------------------------------------------------*/
but this DOES NOT:
/*-------------------------------------------------------*/
import std.range, std.random;
void main()
{
char[] vowels = ['A', 'E', 'I', 'O', 'U'];
static assert(isInputRange!(typeof(vowels))); //pass
auto x = randomSample(vowels, 1); //fail
}
/*-------------------------------------------------------*/
main.d(6): Error: template std.random.randomSample(R) if
(isInputRange!(R)) does not match any function template
declaration
main.d(6): Error: template std.random.randomSample(R) if
(isInputRange!(R)) cannot deduce template function from argument
types !()(char[],int)
