Create a function called _if which takes 3 arguments: a value bool and 2 functions (which do not take any
parameters): func1 and func2
When bool is truthy, func1 should be called, otherwise call the func2.
_if(true, proc{puts "True"}, proc{puts "False"})
# Logs 'True' to the console.def _if(bool, ifTrue, ifFalse)
bool ? ifTrue.call : ifFalse.call
end
