I don't have experience with std.container but I think you need to call take(a, 1).

The following worked for me. Note treating the SList as a range by []:

import std.container;
import std.stdio;
import std.algorithm;
import std.range;

void main()
{
    auto l = SList!int(1, 2, 3, 4, 5, 6, 7);

    auto a = find(l[], 2);      // Search for 2 ...
    l.linearRemove(take(a, 1)); // ... and remove just 2

    auto b = find(l[], 6);      // Search for 6 ...
    l.linearRemove(b);          // ... and remove from there

    assert(l == SList!int(1, 3, 4, 5));
}
