I'm a fan of the ternary operator, but i think an approach like this would be clearer: 
# LHS = Left-hand side
# RHS = Right-hand side
my $s = 'a,b=c,e=#f';
my %h = map {
  $_ .= "=fn($_)" unless /=/;   # add a RHS
  s/#(\w+)/fn($1)/;             # change the RHS '#' notation to the '
+fn' notation
  split( /=/, $_, 2 );          # return the LHS=>RHS mapping (delim'd
+ by a '=')
} split /,/, $s;      # split on commas to get the strings for the pai
+rs
