IsDeclared - Return Value BUG

[mLipok]

Global $_i = 1
MsgBox(1, 'Global', IsDeclared($_i))

Test()
Func Test()
	Local $i = 1
	MsgBox(1, 'Local', IsDeclared($i))
EndFunc   ;==>Test

Expeced 1 and -1

The bug is not where you think it is. Check IsDeclared help page:

Global $_i = 1
MsgBox(1, 'Global', IsDeclared("_i"))

Test()
Func Test()
	Local $i = 1
	MsgBox(1, 'Local', IsDeclared("i"))
EndFunc   ;==>Test

The actual bug is that both calls should return 0 in your posted code.
IsDeclared($_i) --> IsDeclared(1) --> IsDeclared("1") cast since IsDeclared expects a string argument --> 0 since no variable $1 exist.

BTW the latest release (v3.3.12.0) actually returns 0 twice.
I'd to classify as "No bug" if I could login here.

As jchd rightly said this isn't a bug, as a IsDeclared() requires a "string representation" of the variable name.

Global $_i = '_i'
ConsoleWrite(IsDeclared($_i) & @CRLF)

Test()

Func Test()
	Local $i = 'i'
	ConsoleWrite(IsDeclared($i) & @CRLF)
EndFunc   ;==>Test
