I would like to write the following code line without the signs @#%^&*?!

Sequence @@ (XMLNote[#1, m] &) /@ attributes

I have made this code but it seems that it should be a slight difference since I no longer the good result in my program

Apply[Sequence, Map[(XMLNote[#1, m]) &, attributes]]

In fact, I started to use Mathematica not a long time ago and for the moment, I prefer to use a more explicit syntax in my code.

Thank you for you help.

    $\begingroup$ If you detest the nonalphanumerics, you can certainly go further: Apply[Sequence, Map[Function[z, XMLNote[z, m]], attributes]] $\endgroup$ Commented May 23, 2015 at 14:41
  • $\begingroup$ perfect, thank you. And what was the mistake in my translation? Otherwise, I don't detest the nonalphanumerics but when I have nested functions, I'm a bit lost when I have too much nonalphanumerics $\endgroup$

  • $\begingroup$ Before that: could you clarify the " I no longer the good result in my program"? Why did you say that it didn't work anymore after making things all explicit? $\endgroup$ Commented May 23, 2015 at 15:03
  • $\begingroup$ Sorry I made a mistake. The two codes were equivalent. Thank you for your help. $\endgroup$

How about getting Mathematica to do the work for us?

FullForm[Sequence @@ (XMLNote[#1, m] &) /@ attributes ] // HoldForm

Which yields:


These two expressions are formally equivalent in every single way (they are a different syntax for the same thing). If they yield different results, there must be a bug in some other place in the code, or in how each of them is actually used.
