[ruby-core:94300] [Ruby master Bug#10778] `defined?(expr)` should be equivalent to `defined? (expr)` not `(defined? expr)`

< ^ > P N |<>| ^ _>< --- | ~ ...Help

Issue #10778 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Feedback to Rejected

In Ruby, a space before an opening parenthesis often has significant meanings.
Combining `defined?(a)` higher than `&&` is considered reasonable.

----------------------------------------
defined? is an operator not a method, its operand is defined as the expressions to its right.

It does not even require a space: `defined?a`

So `defined?(a)` should be equivalent to `defined? (a)` instead of `(defined? a)`
