String interpolation

[kevlarr]

How could a reference be interpolated in a string?

table person (
    kevin (name 'Kevin')

    (name 'Also ${@kevin.name} too')

Patterns like ${..} or #{..} are common in other languages, but maybe something simpler would suffice, such as automatic concatenation:

table person (
    kevin (name 'Kevin')

    -- Without spaces okay
    (name 'Also '@kevin.name' too')

    -- compared to...
    (name 'Also #{@kevin.name} too')
    
    -- with spaces, too
    (name 'Also ' @kevin.name ' too')

    -- compared to...
    (name 'Also #{ @kevin.name } too')

Feels like the fewer special characters the better, from the perspective of a parser or a reader/typer.

Note: Since a reference could be for a column populated by database, there is no guarantee that the referenced value exists at parse time.
