Steps to Reproduce and Observed Behavior

As shown in the following figure, it is impossible to go to the definition of pool.create() .

code:

const std = @import("std");

pub fn main() !void {

    // .init() have no hover, and cannot "Go to Definition".
    var pool: std.heap.MemoryPool(u64) = .init(std.heap.smp_allocator);

    // .deinit() same as above
    defer pool.deinit();

    // All methods of MemoryPool have no hover, and cannot "Go to Definition".
    const p = try pool.create();
    pool.destroy(p);
}

Expected Behavior

Instances or methods of MemoryPool have hover prompts and can "Go to Definition".
Changing the type definition of the pool to look like the sixth line can achieve the expected result.
