Synced eval or yield function

[trikko]

Hello,

it would be useful to have a blocking version of the eval() function in addition to the asynchronous one: in many cases, the necessary roundtrip to retrieve the value unnecessarily complicates things. Alternatively, if it doesn't disrupt everything, could there be a method to call a single interaction of run() on various platforms? For example, in the case of GTK, something like "gtk_main_loop_iteration.".

In this case, you could launch eval and wait in an infinite loop for the call to be completed, but this loop should be able to trigger the iterations.
