That sounds like heresy :) Would anyone in D community really switch to 
some other language? I'm sure there's a strong emotional bond already. 
Even badly designed features and bugs can be seen as a strength if your 
opinion is heavily biased. Learning a language is an investment. If 
you've invested lot of time and effort in a language, all kinds of 
feelings such as bitterness and frustation come up.

There are people who use several languages in their daily work. But those 
who post on language forums even at 3 a.m. tend to have emotional or even 
religious binds to the language.

I really wonder how much can be done before D3 is out. If there's a 
strict deadline and people want results fast, I really don't expect D3 to 
contain all the features we have planned or suggested already. I'm not 
even sure what features it could bring. IIRC Walter stopped liking the 
idea of powerful macros already. So at the moment e.g. strings + CTFE + 
string mixins are textual macros, but the idiom has been made difficult 
to discourage its use.
