Try either "30 april, 2006" or "2006 april: 30"

I am having fun with dates, and I can build them with the following
expression:
2006 year april dayNumber: 30
I don't like the keyword selector there, because it breaks the beauty of the
expression and forces parenthesis afterwards. It would be nicer if I could
write:
2006 year april 30
It would never had occurred to me that numbers *could* be selectors if I
hadn't taken a look at Forth. In that amazing little language *anything* can
be a selector (eg. #?! or ^%* are valid selectors or word names, as they
call them).
As a comprise, I decided to use the following expression:
2006 year april day30
But that leaves me with another problem. Basically defining 31 methods like
this:
TmActualMonth>>day30
^ self dayNumber: 30
Very boring. In the very Logo way, I created a method that creates those
boring methods:
TmActualMonth class>>installBoringMethods
(1 to: 31) collect: [:number |
self fakeCompile:
(String streamContents:
[:stream |
stream
nextPutAll: 'day';
print: number; cr; tab;
nextPutAll: '^ self dayNumber: ';
print: number ] ) ]
Now I have to rush to our first UK Smalltalk meeting. Stephen Taylor from
APL fame will be giving a presentation. It seems that there are lots of
similarities between the APL and the Smalltalk community. But we are
bigger!!
