MQL5 Standard Library: Generic - Compatible with MT4?

Hey all! I'm working in an EA framework so I can spin strategies up for both MQL4 and MQL5, and I'd like to implement a HashMap, since there's an implementation already done for MQL5 in /Include/Generic/HashMap.mqh, I gave it a shot and moved the folder to MT4 to see what happens. To my surprise

Question about backspace key event for graphical objects
