Do you distinguish between "" and undef/null? Because in Perl, they're not exactly the same, nor are they in SQL, and in Perl they're even hard to test without warnings. I hope your system is more flexible in doing the test. I like Javascript's syntax, where you can directly compare to null.

You said:

Variables do not need declaration, similar to perl without using strict. They default to 0.
Is the default "0" or "", when treated as string? Is it the same as undef/null?

p.s. Your perl pseudocode is off. "my" is written in all lowercase, and 

$interpreter( \%bind_variables )

needs an arrow: 
$interpreter->( \%bind_variables )
