No it's not possible, D is a statically typed language.
Why would you want errors that can be caught at compile time to
happen at runtimes ?

My guess would be this line is causing your trouble. That is
trying to pass an instance as a value at compile time, thus
triggering ctfe.
Since you use the `Array` object inside and that uses malloc
The following program produces an error message and it is not
clear exactly what line causes this error:
module maybe;
@nogc:
private import std.container : Array;
struct MayBe(T) {
Array!T data;
this(T datum) {
data.reserve(1);
data.insert(datu

You could do it with delegates. But it's ugly:

I suspect the problem is using .length rather than some other
size property.
I changed int to size_t and used const(char[]) etc. as suggested.
It ran but crashed. Each crash was a range violation, so for each
one I put in a guard so instead of
if ( ... m_b[m_k])
I used
if (m_k < m_b.length && ... m_b[m_k)
I did this kind of fix in three places.
The result is that it
