ending haml comments

I am new to haml and this is stumping me. I don't like to delete code where I can comment it out but I have no idea how to properly end a comment in haml.

Here is a code snippit:

.field
 = f.label :member_id
 %br/
 = f.text_field :member_id
.field
 = f.label :instrument_type
 %br/

I'm trying to comment out the first field so I used:

/
.field
 = f.label :member_id
 %br/
 = f.text_field :member_id
.field
 = f.label :instrument_type
 %br/

but that commented out everything after the first field.

Then I tried:

/
 .field
  = f.label :member_id
  %br/
  = f.text_field :member_id
.field
 = f.label :instrument_type
 %br/

but it didn't like that either, or:

 -#.field
 -# = f.label :member_id
 -# %br/
 -# = f.text_field :member_id
.field
 = f.label :instrument_type
 %br/

I must be missing something. I looked all over but the examples never show code after the comment.
