This domain provides a table type in which the keys are known to
be strings so special techniques can be used.
Other than performance, the type \spadtype{StringTable(S)} should
behave exactly the same way as \spadtype{Table(String,S)}.
See \xmpref{Table} for general information about tables.
\showBlurb{StringTable}

\xtc{
This creates a new table whose keys are strings.
}{
\spadcommand{t: StringTable(Integer) := table()  \bound{t}}
}
\xtc{
The value associated with each string key is the number of
characters in the string.
}{
\begin{spadsrc}[\free{t}\bound{h}]
for s in split("My name is Ian Watt.",char " ")
  repeat
    t.s := \#s
\end{spadsrc}
}
\xtc{
}{
\spadcommand{for key in keys t repeat output [key, t.key] \free{t h}}
}
