Seeking information about Glass DSLs

[RAbraham]

Hi David,
I'm gathering information for a blog post on DSLs that I'm about to write and I'm really curious about Glas's take on DSLs. I had a few questions if you don't mind answering any of them.

• What were the reasons for making DSL creation an integral part of Glas? In other words, what makes you a believer in DSLs.
• What do you think of the macros(Lisp) vs DSL tradeoff? If one was a programmer knowledgeable in Lisp macros for e.g., would you recommend DSLs to them or are DSLs more meant for non expert programmers?
• Is the grammar PEG or CFG? Or does that depend on the DSL builder?
• If it's not PEG, do you have any reservations against/opinions on PEG?
• My current approach to building DSLs would be defining a PEG grammar/semantics in Ohm JS(https://github.com/harc/ohm). How would building a DSL in Glas differ from that?
• What are some good resources to check out for someone interested in building DSLs. What literature inspired you re: DSLs.

I'm really excited about Glas and what I can learn from it. Thanks!
