I started testing Geany in my work with some perl files and found something quite annoying. Asking here to see if this is intended.
When I open a perl file, the symbols list show me every "my" scoped variable in the file, even those embedded into a function (that is, the kind of variables other languages would call "stack local with static scope"). Is that the way you wanted it ?
In my opinion it is quite annoying to have every local variable shown in the Symbols list, as it is better suited for workspace navigation. As such, I'd say the best option would be to show only "my" global functions (global to file).
