It has been a very long time since -dip25 CLI switch was introduced.
More importantly, it is a requirement for coming DIP1000, which means
that turning it into normal behavior must be prioritized.

I have quickly checked current DMD sources and this seems to be the only
place affected by the switch:

```
  // escape.d
  /* Check for returning a ref variable by 'ref', but should be 'return r=
ef'
   * Infer the addition of 'return', or set result to be the offending
expression.
   */
  if (global.params.useDIP25 &&
     (v.storage_class & (STCref | STCout)) &&
    !(v.storage_class & (STCreturn | STCforeach)))
  {
```

Looks like it is relatively simple to enable that block unconditionally
and turn errors inside it into deprecations.

 Martin would be OK with adding this change to coming release? That way
we will have more time to fix any issues before DIP1000 comes into play.

 DIP1000 comes into play.

It's a bit late for the current release, we're already 2 weeks 
into beta testing and 1 week behind our schedule.
If you meant 2.073 I think that might be fine, but I haven't yet 
catched up with all the scope/RC plans, so I'm unsure about the 
bigger role of DIP25.

No, I was thinking about 2.072 because Walter will certainly want
DIP1000 work to come in 2.073 and that includes DIP25 - would be nice to
get it one release earlier.

If you feel it will compromise coming release too much, I'll make
required change instead in master as soon as 2.072 is finally released
and merged back.

 so I'm unsure about the bigger role of
 DIP25.

It is very simple - DIP1000 implementation assumes -dip25 is active and
enables it automatically.
