# Possible AQUA query syntax ...

# INSTANCE VARIABLES
# checks to see if a value exists, works for hashes and for arrays
@instance.has_value( value ) # value is a value or array of values

#checks to see if a value exists at a certain location
@instance.has_value( value, :at => 0 ) # if integer, assumed to be an integer
@instance.has_value( value, :at => :first ) # could be either an array or a hash key
@instance.has_value( value, :at => :some_key ) # a hash key   

# INTRINSIC VALUES
has_value(value, :at => ...) # same as above for array and hash like objects

# COMPARITIVE OPERATORS
=, ~=, >, >=, <, <= 

# JOINING CONDITIONS
via and, && ... the usual bitwise   

# POSSIBLE USES

# a descendant of an array or hash
Klass.retrieve( fields ) where
  has_value( string ) = 'something'
end

# a descendant of array
Klass.retrieve( fields ) where
  has_value( string, :at => 0 ) = 'something'
end

# a descendant of hash
Klass.retrieve( fields ) where
  has_value( string, :at => :my_key ) ~= /\Asome/i 
end 

# instance variables

Klass.retrieve( fields ) where
  @obj = my_object # aquatic or non-aquatic
end

Klass.retrieve( fields ) where
  @obj <= Time.now and @published = true
