The facilitated computation of an available symbol set at code locations in a dynamic language program, in which the program is executed up to a particular halt point for which an available symbol set is to be generated. At the halt point, a type of a value of a particular variable may be used in order to generate the available symbol set. However, at the halt point, the variable does not yet have a value of a useful type (e.g., null or undefined), which is possible in a dynamic language program. Rather than return an error, the principles described herein returns an arbitrary symbol set anyway. Specifically, the variable had previously been annotated with information represented accessed type information for the variable, even though the variable has not formally been defined. This annotated information may be used to generate the available symbol set.
