[Webkit-unassigned] [Bug 189914] Throws incorrectly a syntax error when declaring a top level catch variable the same as a parameter

--- Comment #1 from seba kerckhof <seba.kerckhof at gmail.com> ---
Other variations with same problem:

Normal function:
function foo(c){try{}catch({c}){}}

Arrow function:
const foo=c=>{try{}catch({c}){}};

Object shorthand literal:
const foo = {
  bar(c){try{}catch({c}){}}
}


Note that it only seems related to destructuring catch clause arguments, e.g. this works:
function foo(c){try{}catch(c){}}
