Why do you think that there is a bug ?

D array literals are dynamic arrays, so the GC is used.

If the function in which resides the call to `updateBy` is 
`@nogc` then it is probable that `updateBy` becomes `@nogc` by 
attribute inference, except that it cant because of the array 
literal.

Possible workaround: if the array literal contains simple values 
that are known at compile time try to declare it `static 
immutable`.
