Yah, something like that. I found align(NNN) underspecified and underpowered for my work with allocators. As a simple matter, NNN must be a literal, not a compile-time expression. You can't even write e.g. align(size_t.alignof), which is fairly basic.

Yeah I noticed the literal requirement as well and thought it was quite odd...
