I suspect constness (or purity, safety, etc.) mismatch at work, as it does spawn this kind of shitty diagnostic at times.
e.g. 'this' pointer is const in a given context thus it can't call non-const function line.

I suspect it could be simplified further by someone who understands DMD/phobos better than me:

Well whenever it's implemented it's going to be a huge win for my C++
wrapper generator which supports pass-by-value for POD types (unlike
SWIG which requires a pointer and possibly a malloc+free call).
Looking forward to that day. :)

On the plus side, relatively few structs contain mixed float/int members.
