Overview

SymBeg represents the beginning of a symbol literal.

:symbol

SymBeg is also used for dynamic symbols, as in:

:"symbol"

Finally, SymBeg is also used for symbols using the %s syntax, as in:

s[symbol]

The value of this node is a string. In most cases (as in the first example above) it will contain just “:”. In the case of dynamic symbols it will contain “:‘” or “:"”. In the case of %s symbols, it will contain the start of the symbol including the %s and the delimiter.
