<br><br></div><div>Hi! Please could you help me understand smalltalk capabilities in
<br>metaprogramming? Q: could I construct arbitrary message by program? Create
<br>keywords from strings and than build sequence of them to make a message. Mm?
<br>Or may be store keywords in variables and then pass variables withing
<br>messages extracting stored keywords?
<br>Am I dreamer?)
