Even back in 2010 it took about 10 evenings to get it to "runnable" 
state. Then another ~20 evenings to fix most of bugs, including semantic 
errors and GC collecting live objects.

You may want to check my fork that used to compile with dmd 2.058 or 
smth (whatever was actual in 2012). Might help to assess the amount of 
work...
https://github.com/DmitryOlshansky/DMDScript

It at least passed about 90% (most fails in library tests) of 2012 
Google's Spuntik JavaScript test.
