Description

I have created several powershell modules for enterprise system and the number of parameters commands need to support is always at odds with making them easy to use. Often I find myself creating helper functions that just bind parameters to other functions. If the new-alias command allow users to create new alias that already set some options simplified versions use cases could be provided.

An example would be if I wanted to curry get-childitem so that it searches files only
It would be nice if I could do the following

<code>
>Set-Alias getfiles -Value "Get-ChildItem -File"
>getfiles -r -filter foo
</code>

This can be simulated using the following idiom but the user loses all the power of the cmdlets and supporting the many possible parameter sets is unworkable.

<code>
function getfilesfn($filter = "*"){Get-ChildItem -Filter $filter}
getfilesfn get*
</code>

If we were able to curry cmdlets whole apis could be developed using aliases alone.
