Deactivates the trace.

Returns true if the trace was enabled. Returns false if the trace was disabled.

Example

trace.enabled?  #=> true
trace.disable   #=> true (previous status)
trace.enabled?  #=> false
trace.disable   #=> false

If a block is given, the trace will only be disabled within the scope of the block.

Example

trace.enabled?  #=> true

trace.disable do
  trace.enabled?
  # Only disabled for this block
end

trace.enabled?  #=> true

Note: You cannot access event hooks within the block.

Example

trace.disable { p tp.lineno }
#=> RuntimeError: access from outside
