Pash does not support optional arguments

[vladimir-aubrecht]

Pash does not support optional arguments right now. Would be nice if literals and variables would be supported as in Powershell.

For example:

$FallbackEnvironment = "test"

function Get-Consumers-By-Consumer-On-All-Databases(
    $Environment = $FallbackEnvironment # This line will fail
)
{
}

With error:

Parse error at (67:29): Syntax error, expected: ,, )
>     $Environment = $FallbackEnvironment
                                         ^
  +CategoryInfo: ParserError, Reason: ParseException
  +FullyQualifiedErrorId: Parse

In fact it does work, but only if the line after the optional argument is delimited by either , or ).
So this works

function Test-OptArg($a, $b=1,
$c = 2)
{
  $a + $b + $c
}

So Test-OptArg 7 returns 10.

This is very likely to be a grammar issue.
