I meant - of course - something besides `expect`. I was 
responding to your "this tool", thinking that it must refer to 
your new proposal, because otherwise why would there be a 
discussion? But apparently you meant "expect". Then there is no 
debate:
when writing D for microcontrollers today (i.e. you need to use 
GDC or LDC) you have the option to use the equivalent of 
`expect`. Use it.

I'm sorry for entering this discussion and will leave. I do not 
get a sense that the desire is to build a balanced view and come 
to a shared conclusion.
