Re: [Duro-devel] binding D to other languages

[Rene H. <reh...@t-...>]

Tcl was designed from the beginning to be extensible. So although I 
never wrote an extension for Python, Perl, PHP or Ruby I think it's 
easier to write a D extension for Tcl than for other languages. As in D, 
there are no pointers or references in Tcl, only values and variables. 
So there is some conceptual similarity (although D and Tcl are very 
different in other respects).

Actually, Duro started as a C library. The Tutorial D interpreter came 
later. But a true D requires a separate language. The problem is that 
for many people 'relational == SQL'. It's an uphill battle because SQL 
dominates the DBMS market so much that there is not much room for a 
relational alternative.

I'm thinking about a PHP interface so it will be possible to write PHP 
web applications using Duro. But from what I read about extending PHP I 
would have to make the interpreter thread-safe first.
