[Seaside] question on tutorial - contact manager

[sergio_101]

i may have just missed the explanation.. but i am seeing a new syntax
that i don't understand here:

http://book.seaside.st/book/fundamentals/forms/drop-down


Contact>>gender
    ^ gender ifNil: [ gender := #Male ]
Contact>>isMale
    ^ self gender = #Male
Contact>>isFemale
    ^ self gender = #Female

i don't understand the hash in front of the gender.. did i just gloss
over something?

thanks!
