Current coverage is not bad (70+%) and in general and I don't want to embark on one of those 100%-coverage crusades. But I know there are parts of the interpreter that are undertested (and don't generally need a whole lot of tests) and it might be nice to get some quick wins in terms of coverage.

these should return a string representation that is legal YASL code.

for example:

const x = 'string'
echo x           # string
echo x->repr()   # 'string'

Strings will be quoted, certain characters will be escaped, etc.

list.repr and table.repr will behave recursively.

Possibly, we need a set.repr as well.
