#<=(expr) ⇒ Object
Add support of the left arrow operator.

# File 'lib/HDLRuby/hruby_high.rb', line 4564 def <=(expr) self.to_expr <= expr end |
#call(obj = nil, &ruby_block) ⇒ Object
Create an array whose number of elements is given by the content of the current array, filled by +obj+ objects. If +obj+ is nil, +ruby_block+ is used instead for filling the array.
