Description Joseph Rushton Wakeling 2013-08-25 04:55:04 UTC 
Created attachment 1244 [details]
Example with std.random.Random wrapped by RefRange.  .min and .max properties are not forwarded.

When a range is wrapped by RefRange, _all_ the public methods and properties
should be forwarded.

The attached example shows a case where std.random.Random is wrapped by
RefRange.  The regular range methods/properties are correctly forwarded, but
the .min and .max properties of Random are not, and the code fails with the
errors:

refrange.d(26): Error: no property 'min' for type
'RefRange!(MersenneTwisterEngine!(uint, 32, 624, 397, 31, 2567483615u, 11, 7,
2636928640u, 15, 4022730752u, 18))'
refrange.d(27): Error: no property 'max' for type
'RefRange!(MersenneTwisterEngine!(uint, 32, 624, 397, 31, 2567483615u, 11, 7,
2636928640u, 15, 4022730752u, 18))'

Desired behaviour: .min and .max properties should be present for
RefRange!Random.

This is where it would be nice if the language supported alias *p this. :)

See also Issue #14830 for a similarly problematic issue with RNGs and RefCounted.
