You probably talk about something like :

Assuming an instance method called #doSomething the following are identical:

myInstance doSomething
myInstance perform: #doSomething

Subject: [Pharo-project] Method expressed as symbol, used as argument

It was pointed out that given an instance method
  MyClass >> doSomething 
that
  MyClass do: [:each | each doSomething].
can be expressed as 
  MyClass do: #doSomething.

Can someone suggest something to read that explains the usage of #
here (#doSomething), the relation of methods to symbols, etc. 

Trying to wrap my head around it. Thanks.
