Compilers upset while away in bar temporarily (7)
I believe the answer is:
suspend
'bar temporarily' is the definition.
(I've seen this before)
'compilers upset while away' is the wordplay.
'compilers' becomes 'us' (the compiler and their colleagues).
'upset' is a reversal indicator.
'while away' becomes 'spend' (I've seen this in another clue).
'us' backwards is 'su'.
'su'+'spend'='SUSPEND'
'in' acts as a link.
(Other definitions for suspend that I've seen before include "Fail to hit" , "Temporarily halt; hang" , "Hold up or dangle" , "Adjourn" , "Put in abeyance" .)
