Is Powershell Polymorphic?

Question

I would like to write some functions that take a single parameter which could vary the type without having to use a whole new function.

For instance for SQL, I would like to either accept sql command text string or a file. or for active directory either the path or the adsi object would be taken

unlock-aduser [adsi]"LDAP://dn=..." or unlock-aduser [string]"LDAP://dn=..."

would work just as well.

For the record, I'd say this is not polymorphism but function overloading. — J.N., Mar 01 '11 at 14:48
Not by everybody's definition. http://stackoverflow.com/questions/154577/polymorphism-vs-overriding-vs-overloading/154675#154675. I think not because when you use overloading the behavior is the same, but the inputs are different, while when you use polymorphism you tend to have the same inputs but a different behavior. — J.N., Mar 01 '11 at 14:56

Simply No its not.
