import std.range;

alias string[] surrealNum_segments;
alias ElementType!surrealNum_segments[string] surrealNum_segments_withID;

Or, if you don't like writing all that (say, you have 1e8 array types you want 
ID versions of):

template FOO(T : U[], U) {
     alias U[string] FOO;
}

alias FOO!surrealNum_segments surrealNum_segments_withID;

But no, there is no built-in function of this kind.
