Sorry..
I mean:
auto X = "100000000000000";
auto N = X.insertInPlace(3,',');

I have a string X and I need to insert a char in that string...

I try this:

auto N = X.insertInPlace(1,'0');
`std.array.insertInPlace` doesn't return anything. "In place"
here means "in situ", i.e. it will not create a new string, but
insert the new elements into the existing one. This operation may
still reallocate, in which case the array slice you're passing in
will be updated to point to the new memory.
Either use this instead:
auto x = "100000000000000";
auto n = x.dup;
n.insertInPlace(3, ',');
// or: insertInPlace(n, 3, ',');
... or use slicing and concatenating to construct a new string:
auto g = x[0 .. 3] ~ ',' ~ x[3 .. $];
(Side note about style: It's common practice to use lower-case
names for variables, upper-case first letters are used to denote
types. But of course, that's a matter of taste.)
