# PowerShell can infer generic <T> for method calls for your, when it has a parameter of the same type <T>
# Example: Enumerable.Distinct<TSource>(IEnumerable<TSource>)
# TSource can be inferred from the argument
[System.Linq.Enumerable]::Distinct([int[]]@(1,2,3,1,2))

# Let's say you want to call a generic method without ability to infer types.
# Example: Enumerable.OfType<TResult>()
# Idially you may expect syntax like this
# [System.Linq.Enumerable].OfType[int](@(,@(1,2,'a'))
# where you tell PowerShell type explicitly.
