Don’t limit ourselves to plain ASCII encoding:

scriptencoding utf-8

Enforce vim script implementation to reduce ambiguities and improve robustness:

scriptversion 4

Bail early if conceal isn’t supported:

if !has('conceal')
    finish
endif

Show pretty bullets for unordered lists:

syntax match rstList "^[*-]\ze "hs=e conceal cchar=•
syntax match rstList "^\s\+[*-]\ze "hs=e conceal cchar=◦

Note

I only use * and - for list prefixes, so these won’t work for everyone. However, including all the reST prefix options opens the door for a lot of incorrect highlights without massively increasing the complexity.

Sample reST lists with conceallevel=2

Show pretty markers for ordered lists:

for s:n in range(1, 10)
    execute printf('syntax match rstList "^%d\.\ze " conceal cchar=%s',
    \              s:n, nr2char(9'351 + s:n))
endfor
for s:n in range(1, 12)
    execute printf('syntax match rstList "^\s\+%d\.\ze "hs=e-1 ' ..
    \              'conceal cchar=%s',
    \              s:n, nr2char(8'559 + s:n))
endfor
