Type casting when declaring a variable does not work

[dalexeev]

Godot version:
3.1.1.stable.official
3.2.alpha2.official

OS/device including version:
5.2.20-1-MANJARO

Issue description:

See examples:

var x = "abc"
var res: bool = x
print(res) # prints 'abc'
print(res == true) # Error: Invalid operands 'String' and 'bool' in operator '=='

var x = null
var res: String = x
print(res) # prints 'Null'
print(res.length()) # Error: Invalid call. Nonexistent function 'length' in base 'Nil'

It works (but the icon is wrong, by the way):

If the code still have problem.I think it may the program didn't do the type casting, so try another way to do the type casting. For example convert boolen into string: .toString()

Probably, it's a bug. See #31331 (comment)
