“M” For Language Definition in November 2009 CTP

I couldn’t wait for the PDC, so I posted a screen shot of my favorite new three features of “M” for defining domain-specific languages (DSLs) in the November 2009 CTP of “Oslo”:

• Expressions on the right-hand side in language actions to calculate results. “M” supports a rich expression syntax for a variety of data types.

• Data conversion functions for output, one for each of the supported “M” data types.

• DSL debugging mode to let you step through your input data and debug your language.

I can’t wait for you to see it!
