Dynamic Casting

Suppose you want to do something like:

$t = Read-host -Prompt "Type: "

$v = Read-host -Prompt "Value: "

[$t] $myVar = $v

In this case -as doesn't help. What to do?

I blogged about this a few weeks ago, explaining how it can be used to ease the pain of using Enums in powershell:

This is probably a more practical example of dynamic casting. ;-)

This is not working for me. Powershell keeps going into an endless loop. The command I tried is "Joe Brinkman" -as "[PowerShellExpert]" and it just isn't working? What am I doing wrong? ;-)

Sounds great - really looking forward to all the new goodies:-)

But instead (as well) as dynamic casting, can we have dynamic locales?

12/25/2007 is not a valid date in my environment and you have no idea how inconvenient it is to remember that valid date strings will (sometimes!) be rejected by a cast to [datetime].

Sorry to go on about it. I know I've brought this up before, but it's the only REAL bad thing to have crept in to v1.0 IMO and I wish you guys would make it better.

Thanks
