Paragraph with only one line.

Paragraph trailed by comment. ## This is the comment

Paragraph split
over multiple lines.

  Paragraph split ## with an indent!
over multiple lines ## Another sneaky comment
with a comment trailing some.

#tag{This} paragraph starts with a simple tag.

This paragraph ends with a simple #tag{tag.}

This #tag{paragraph} has a few #tag{tags}.

#a{}b#c{}#d{}

This paragraph has a number of inline tag styles.
#tag              ## no meta, no children
#tag[]            ## no meta, no children
#tag[]{}          ## no meta, no children
#tag[prop]        ## 1 prop, no children
#tag[prop1,prop2] ## 2 props, no children
#tag[set = '42']  ## 1 setting (equal, single quote), no children
#tag[set = "42"]  ## 1 setting (equal, double quote), no children
#tag[set: '42']   ## 1 setting (colon, single quote), no children
#tag[set: "42"]   ## 1 setting (colon, double quote), no children
#tag[prop, foo: 'bar', baz = "quz"] ## complicated, no children
#tag{content}     ## no meta, children
#tag[]{content}   ## no meta, children
#tag{#tag{ok}}    ## no meta, children containing tags
#tag[prop, foo: 'bar', baz = "quz"]{#tag{ok}} ## ok wow
#tag[

#tag[ ## Comments can go here
  ## Because items in the metadata block are relatively structured
