I'm not very concerned with any speed improvements (though I do often run tests that go for 4-8 hours on my dual Opeterons when researching many trading systems). However, adding structures and classes are absolutely something to get excited over IMHO. When creating simple systems, the lack of structures can sometimes be a nuisance, but when creating complex or large systems, the lack of any customizable structure is absolutely crippling. Although many people may not like the idea of converting from MQL4 to MQL5, I for one am more than willing to do the conversion.

One thing to note is that the actual conversion from MQL4 to MQL5 should not require much modification at all. MQL4 is basically a very limited version of C. MQL5 is positioning to be a very close replication of C++. I wouldn't be surprised at all if they don't change the built-in functions they've provided and that most MQL4 code will run without modification on the MT5 platform. That assumes they don't change the functions they use in MQL4.
