Why do you prefer the FORG error?

I will fix the rest editorially.

Ah, I see the problem - the examples attempt to catch static errors:

#

A try/catch expression without a CatchErrorList catches any error:


The CatchErrorList in this try/catch expression specifies that only err:XPST0051 is caught:

try {
    $x cast as integer
}
catch err:XPST0051 {
    0
}

#

The CatchErrorList in this try/catch expression specifies that errors err:XPST0051 and err:XPST0032 are caught:

try {
    $x cast as integer
}
catch err:XPST0051 | err:XPST0032 {
    0
}


I'll fix that, you can't catch a static error.

Fixed, will show up in next internal commit.
