Hi,
the following code has been working before:
\starttext
\startMPpage[instance=decimalfun]
draw function(1,"x","x*sin(x)",0.5,1,1/100) scaled 1in;
\stopMPpage
\stoptext
Now (with an updated ConTeXt) I get an error:
metapost > loading 'metafun' as 'metafun.mpxl' using method 'decimal'
metapost > initializing number mode 'decimal'
metafun > log >
metafun > log > error: Missing ')' has been inserted
metafun > log >

metapost > log > (
metapost > log > <scantokens> x*sin(
metapost > log > x)
metapost > log > <to be read again>
metapost > log > )
Maybe I have done something wrong earlier, but I cannot see any
unmatched parenthesis now.

sin is just not defined in decimal mode (in scaled and double they use
the math library) .. so i'll fix that
