https://issues.dlang.org/show_bug.cgi?id=20483 --- Comment #2 from hsteoh@quickfur.ath.cx --- The problem is caused by the implementation of Grapheme.opSlice(), which returns a proxy range object that contains a pointer to the parent Grapheme. A cursory glance at the code didn't show any obvious reason why this was done this way; conceivably the proxy object returned by .opSlice could just copy the necessary data from Grapheme instead of retaining a pointer to it. This implementation choice makes it hard to work with Graphemes in range-based pipelines. If anywhere in the pipeline a Grapheme is generated on-the-fly, it will generally be returned from .front as an rvalue, and therefore even the ref trick mentioned in this bug will no longer work. I recommend to change the implementation of .opSlice so that it does not retain a pointer to the parent Grapheme. -- |
