Annoying IntelliSense behavior with multiply defined variables (18.3.0 Insiders [11109.51.main] but probably also 17.14) #80730
Description
IntelliSense doesn't list ambiguous variables (e.g. variables that are multiply defined) leading to some unfortunate behavior if quickly type something followed by expecting the variable.
I am rewriting this function to add “double width” to the parameter list. Note this causes an error on line 90 – since I define a local variable of that name there – but there is no indication of an error on line 73.
I then – on line 83 – type “if (wid” expecting to get the width parameter but instead – before the tab – I get this, so tab selects CaretWidthOption. Imagine how confusing this is if I’m working in a larger function.
My expectation is that things like IntelliSense would use the preceding definition of width rather than suppressing it entirely because there’s an error or ambiguity.
