Excess whitespace before '(' (E211)
Open parentheses should not have any space before them in function, sub, and property declarations or calls.
Anti-pattern
' The space after Foo is unnecessary
Function Foo (Bar)
End Function
Best practice
Function Foo(Bar)
End Function
Exceptions
This rule is not universal and only applies in a few contexts. Whitespace must exist before parenthesised expressions and in declare statements.
Public Declare Foo "Bar" (Baz)
Function Foo(Bar)
If (Bar > 6) Then
Foo = 3 * (1 + 2)
End If
End Function
