Bring back rerun(), or adjust map()?

[lmiratrix]

I run a lot of simulations, and relied heavily on rerun(). The current view is this should be replaced with map( 1:R, ~ one_run() ) rather than rerun( R, one_run() ). But this makes it hard to pass arguments through to one_run() since the map version makes the anonymous function take an extra ID number, which is often not particularly useful for the one_run() call.

E.g., consider passing through triple dots like this:

func = function( x, ... ) {
  cat( "func - x = ", x, "\n" )
  print( list( ... ) )
  
}

func_wrap <- function( r, ... ) {

  cat( "func_wrap:\n" )
  print( list( ... ) )
  
  func( 10, ... )
  
  res <- map( r:(r+1), ~ {
    cat( "** map tick\n" )
    func( x=4, ... ) } )
  
  invisible( res )
}


func_wrap( 4, a=2, b=3 )

This has ties to the behavior noted in #1118 (which I flagged before, but this keeps coming up for me--I am posting this as it seems a different take on the original issue)
