Yes, there are pros and cons, and of course it's a matter of taste (and
eye vision). Compare

   foo(long.argument = safdsf, delim_arg = 343, funnyArg_sfd = sdfdf(sdfds))
   
   foo(long.argument=safdsf, delim_arg=343, funnyArg_sfd=sdfdf(sdfds))
   

And now spread across lines:
   
   foo(long.argument = safdsf,
       delim_arg     = 343,
       funnyArg_sfd  = sdfdf(sdfds))
   
   foo(long.argument=safdsf,
       delim_arg=343,
       funnyArg_sfd=sdfdf(sdfds))


Before 12.09 we didn't have highlighting of "=", now it can be easily
activated. So it's even less of a problem now.

In general I feel that more sparse the code is, easier it is to
read. That includes spaces in "if( ", "for( ", " = " and various empty
lines inside functions to delimit declarations, main body, return values
etc. I literally force myself to put spaces and empty lines in the code,
because I know it will be much easier to read later.
