I imagine Imperatorn is quite familiar with postblit and was pointing 
out that it is strange to use postblit constructor, which is deprecated, 
in a "new implementation".

The original post was long and really buried the lede, but OP was 
pointing out what looks like a compiler bug: a linker error referencing 
a postblit symbol only shows up when compiling with DMD or with LDC 
earlier than 1.25.

Can someone give some insight?
