    Introduce ghci command wrapper
    
    Introduce ghci command wrapper, which can be used to cutomize ghci:
    * process additionals actions before/after the command
    * handle particular exceptions in given ways
    * logging stats
    
    We also split the timing and printing part of `timeIt` into different
    functions.
