Templates don't exist until compile time, until you build the code, the IDE plugin doesn't have the full data on what types exactly are there. Java/C# generics are more limited in functionality, but it's a tradeoff in exchange for better ahead of time knowledge of types.

Visual Studio can do that, you just provide an example type and the IDE shows what the result would be.

Now try that on vim.
