Time execution.
Profile execution of an expression. This command compiled exp and
then runs it within the statprof profiler, passing all keyword options
to the statprof
procedure. For more on statprof and on the the
options available to this command, See Statprof.
Trace execution.
By default, the trace will limit its width to the width of your terminal, or width if specified. Nested procedure invocations will be printed farther to the right, though if the width of the indentation passes the max-indent, the indentation is abbreviated.
These REPL commands can also be called as regular functions in scheme
code on including the (ice-9 time)
module.
