Hi All

��

This is an idiot question, I should know the answer, but I have looked around and can���t find relevant documentation. I���m not asking for a full answer, just a pointer as to where to start looking.

��

I have seen from examples in this forum that an expression like the following:

��

paras collect: [para| para prettyPrinted]

��

can be written more concisely as:

��

paras collect: #prettyPrinted

��

which obviously works when I try it. It doesn���t seem to fit in with the definition of #collect:, which requires a block as argument. Where can I find the relevant definition, either in method comments or in some general manual? Can the notation be extended,

for example to #select: - obviously with an argument which returns a Boolean? Can it be used with a method which requires an argument, e.g. as myArray collect: (#myMethod: arg)? Are there any other extensions?

��

Any help gratefully received.
