Strange..., why '@' ?

That means to!int failed because 'val' contained a '@' character in it:

import std.conv;

void main()
{
    auto s = "42@";    // <-- What is that?
    auto i = to!int(s);
}

However, there seems to be a bug in to(). It seems to incorrectly go one character ahead:

    to!int("mn");

"Unexpected 'n' when converting from type string to type int"

    to!int("m");

"Unexpected end of input when converting from type string to type int"

That is a bug, right?

So, in your case the unexpected '@' character may be after another unexpected one:

    to!int(" @");

"Unexpected '@' when converting from type string to type int"
