// 'MyInvocation.MyCommand.Parameter', it's actually retrieving the parameter metadata of the same cmdlet that is currently
// running. In this case, information about the specified parameters are not kept around in 'MyInvocation.MyCommand', so
// going through the binding algorithm again won't give us the metadata about the dynamic parameters that should have been
// discovered already.
// The fix is to check if the CommandInfo is actually representing the currently running cmdlet. If so, the retrieval of parameter
// metadata actually stems from the running of the same cmdlet. In this case, we can just use the current CommandProcessor to
// retrieve all bindable parameters, which should include the dynamic parameters that have been discovered already.

// It is usually used by TryStatement and TrapStatement, which makes the general exception catch-able.
//
// For the 'Clean' block, we don't want to bubble up the general exception when the command is enclosed
// in a TryStatement or has TrapStatement accompanying, because no exception can escape from 'Clean' and
// thus it's pointless to bubble up the general exception in this case.
//
// Therefore we set this property to 'false' here to mask off the previous setting that could be from a
// TryStatement or TrapStatement. Example:
// PS:1> function b { end {} clean { 1/0; Write-Host 'clean' } }
// PS:2> b
// RuntimeException: Attempted to divide by zero.
// clean
// ## Note that, outer 'try/trap' doesn't affect the general exception happens in 'Clean' block.
// ## so its behavior is consistent regardless of whether the command is enclosed by 'try/catch' or not.
// PS:3> try { b } catch { 'outer catch' }
// RuntimeException: Attempted to divide by zero.
// clean
//
// Be noted that, this doesn't affect the TryStatement/TrapStatement within the 'Clean' block. Example:
// ## 'try/trap' within 'Clean' block makes the general exception catch-able.
// PS:3> function a { end {} clean { try { 1/0; Write-Host 'clean' } catch { Write-Host "caught: $_" } } }
