[Newbies] #and:, #or: methods in blocks?

[Petr Fischer]

Hi,

methods #and:, #or: etc. are defined in Boolean class only - why this  
methods are not defined in "blocks" too?

* standard way (brackets mix):
( condition_1 ) and: [ condition_2 ] ...

* this (fictive) way looks beter (for me):
[ condition_1 ] and: [ condition_2 ] ...
more complex one: [ [ cond_1 ] and: [ cond_2 ] ] or: [ cond_3 ]

Thanks for clarification, pf
