I thought the following would terminate gracefully having printed 0..9 in some (random) order:
#! /usr/bin/env rdmd
import std.algorithm ;
import std.range ;
import std.stdio ;
import core.thread ;
int main ( immutable string[] args ) {
auto threads = map ! ( ( int a ) {
void delegate ( ) f ( ) {
return delegate ( ) { writeln ( a ) ; } ;
}
return new Thread ( f ) ;
} ) ( iota ( 10 ) ) ;
foreach ( t ; threads ) { t.start ( ) ; }
foreach ( t ; threads ) { t.join ( ) ; }
return 0 ;
}
However, this does not happen, at least with 2.059 on Linux as per
Debian Unstable. Instead I get:
1
2
4
5
8
3
7
6
9

I think I must be having a dumb moment as my reaction continues to be
WTF.
