Description Simen Kjaeraas 2010-10-13 11:48:54 UTC 
ref int delegate( ref int ) r = ( ref int a ) { return a; };

The above gives "found 'ref' instead of statement"

Still happens on latest git HEAD. :-(
Comment 2 Walter Bright 2014-12-08 05:14:01 UTC 
You can do it with an alias:

    alias ref int delegate(ref int) dg_t;
    dg_t r = ...;
