I prefer:

   if !get(a:map, 'expr')

The 0 is default and the space after ! is unnecessary, IMHO.

let a:map.rhs = string(a:map.rhs)
endif

silent execute 'inoremap <expr><silent><nowait><buffer>' l:lhs
\ l:wrapper . '("' . escape(l:lhs, '\') . '", ' . string(a:map.rhs) . ')'
\ l:wrapper . '("' . escape(l:lhs, '\') . '", ' . a:map.rhs . ')'

let s:created_maps += [a:map]
endfunction
