           Summary: Multiple execution of 'static this' defined in template
           Product: D
           Version: 1.030
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: samukha@voliacable.com


File a:
----
module a;

import b;

alias Foo!(int) foo;

void main()
{
}
----


File b:
----
module b;
import std.stdio;

template Foo(T)
{
   T x;
   static this()
   {
      writefln("Initing " ~ T.stringof);
      T x = T.init; // less trivial initialization here.
   }
}

void baz()
{
    alias Foo!(int) bar;
}
----

Output:
Initing int
Initing int


Note that the constructor is executed only once if we move 'alias Foo!(int)
bar;' out of baz() to the scope of module b.

'T x = T.init;' in the template should read 'x = T.init;', sorry:

File a:
----
module a;

import b;

alias Foo!(int) foo;

void main()
{
}
----


File b:
----
module b;
import std.stdio;

template Foo(T)
{
   T x;
   static this()
   {
      writefln("Initing " ~ T.stringof);
      x = T.init; // less trivial initialization here.
   }
}

void baz()
{
    alias Foo!(int) bar;
}
----
