Vista - Is it possible to create a Constant variable?

As the subject says, is it possible to create a constant variable?

I was able to set "ReadOnly" option for variables (that i actually wanted to
declare as constants) but setting the variable option to "Constant" complains
that I need to declare a variable as a constant during creation time of a
variable

[^_^]PS[167]>$a = "constant string"
[^_^]PS[168]>(gi a).options = "Constant"
Exception setting "Options": "Existing variable a cannot be made constant.
Variables can be made constant only at creat
ion time."
At line:1 char:8
+ (gi a).o <<<< ptions = "Constant"

Is there a special keyword to create a constant variable? or is creating a
constant available only through Cmdlets in the current version of PowerShell?

Yes, use the new-variable command.

% new-variable -Option Constant varName "value"
% $varName
value
% $varName = 5
Cannot overwrite variable varName because it is read-only or constant.

But that does involve using a cmdlet.

I think he meant "Is the ability to create constant variables limited to
Cmdlets?"

And I guess it is, but thankfully there's a Cmdlet that exposes the
ability to the shell. :-)

Ah, by the above statement, hmm i meant creating a custom cmdlet in .NET
I should have been more elaborate on describing what I really wanted to
accomplish. Sorry about the confusion there~
