Seems to me the difference between 

name: my name, id: 0, number of agents: 200, target function: 30sphere,
maximum error: 1e-10, visualize

And this

TrialRun name: 'my name'; id: 0; numberOfAgents: 200; targetFunction:
#30sphere; error: 1e-10; visualize: true

Are so trivial, why bother with the parsing step at all, just use direct
Smalltalk syntax, if kids can learn Smalltalk, so can users of a DSL.  As
far as samples of DSL's go, I use one daily in the Seaside framework for
generating html http://www.seaside.st/Documentation/GeneratingHTML/, and
another http://scriptaculous.seasidehosting.st/, for generating JavaScript.
Both I think are good examples of embedded DSL's in Smalltalk in daily use.
