Bug #19087
closedString#to_c supports multiple "_"
Description
I've noticed a minor inconsistent behaviour of String#to_c
method. It does not treat a sequence of _
character as an end of meaningful characters:
"123".to_c # => (123+0i)
"12_3".to_c # => (123+0i)
"12__3".to_c # => (123+0i)
"12___3".to_c # => (123+0i)
Similar methods #to_i
and #to_r
treat multiple _
in a different way - they just ignore characters after it:
"12__3".to_i # => 12
"12__3".to_r # => (12/1)
I would expect #to_c
to behave similarly.

[Bug #19087] Disallow successive underscores in Complex string

I agree that the new behavior is consistent and preferable, but I don't think it should be fixed on the stable branches.
If there are any troubles on the real world applications with this issue, please let me know.
