Re^2: Extending a perl program with Scheme, Lua, or JS

Thanks, Marpa looks nice. I couldn't get the sample program to run, though:

Can't locate object method "parse" via package "Marpa::R2::Scanless::G" at b.pl line 24.

I guess the other disadvantage is that I would then have to design and implement my own language using Marpa. This could be simple for very simple arithmetic operations, but inevitably I can imagine then having to extend it. Probably better to start with someone else's good design and implementation.

Maybe your version of Marpa is too old? Consult `perldoc Marpa::R2` [download] locally instead of the online manual of the latest version. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]
