Description

Prevent mistake, when mean to use try-finally in try-catch.

Fail

try {
  try {
    doSomeThing()
  } catch { // <- Typo, should be finally
    // Clean up
  } 
} catch {
  // Handle error
}

Pass

try {
  try {
    doSomeThing()
  } finally {
    // Clean up
  } 
} catch {
  // Handle error
}

Additional Info

I was thinking proposal this to no-useless-catch at first, but in this case the catch block not actually "useless", since it could mean to catch error thrown by inner catch block.
