Beginners' languages can have advanced features too
C# introduced some very useful concepts in version 2: generics, the
yield statement, and anonymous methods (which are similar to closures). However, VB.NET was largely left behind: it has generics, but it still misses out on both the
yield statement and anonymous methods, and it had to wait until version 2 to get the simple but convenient and frequently used syntactic sugar of C#’s
C’mon, Microsoft, these are pretty useful language constructs. Sure, a lot of developers don’t know what they are or how to use them, but once you’ve seen how powerful they can be, you wonder how you managed to get by without them. It seems that in .NET land, VB is definitely a second class citizen, perhaps more comfortable for novices to use, but with some gaps in the feature set that will irritate more advanced developers.
PHP suffers the same dumbing-down problem. It has seen massive improvements in version 5 since version 4, but there are still some fairly major gaps that are not likely to be filled in the foreseeable future. For example, apparently Rasmus Lerdorf is of the opinion that PHP is not likely ever to get closures because most PHP developers would not have a clue what to do with them.
Just because a language’s core constituency is dominated by beginners doesn’t mean you should leave out useful features that advanced developers can use. Don’t forget that experienced coders often have to use VB and PHP too.
